    ABSTRACT: Vanadium(V) oxidation of lactic acid shows first order dependency on lactic acid, vanadium(V), H+ and HSO4-. These observations remain unaltered in the presence of externally added surfactants. The effect of adding a cationic surfactant (CPC), anionic surfactant (SDS) and neutral surfactant (TX-100) has been studied. CPC inhibits the reactions while SDS and TX-100 accelerate the reaction to different extents. Observed effects have been explained by considering the hydrophobic and electrostatic interaction between the surfactants and reactants

    ABSTRACT: The oxidation of the binary complex chromium(III)-uridine, [Cr III (Urd) (H2O)5]3+ and the ternary one chromium(III) uridine aspartic complex, [CrIII(Urd)(Asp) (H 2O)3]2+, by periodate have been studied kinetically in aqueous solution to yield CrVI, over 20-40°C and the 2.62-3.68 pH range. The oxidation of [CrIII(Urd)(H 2O)5]3+ by periodate, obeys the rate law, rate = [CrIIIurd(H2O)5]3+ [H 5IO6]{k4K5 + (k5K 6K2/[H+)}, while the reaction of [Cr III(Urd)(Asp)(H2O)3]2+ with periodate following the rate equation d[CrVI]/dt = (k 6K8[CrIII]T[IO4-])/ {1 + K8[IO4-] + ([H +]/K7)}. Thermodynamic activation parameters have been calculated.

    ABSTRACT: The kinetics of oxidation of [Cr III(Dpc)(Pro)(H 2O)] (Dpc = dipicolinic acid and Pro = proline) by N-bromosuccinimide (NBS) in aqueous solution have been found to obey the equation: d[Cr VI]/dt = {(k 3K 2 + k 4k 1k 3/[H +]) [NBS] [Cr III] T} /{1 + (K 1/[H +]) + (K 2 + K 1K 3/[H +]) [NBS]} where k 4 is the rate constant for the electron transfer process, K 1 is the equilibrium constant for deprotonation of [Cr III(Dpc)(Pro)(H 2O)], and k 2 and k 3 are the pre-equilibrium formation constants of precursor complexes [Cr III(Dpc)(Pro)(NBS)] and [Cr III(DpC)(Pro)(OH)(NBS)] -. Values of k 4 = 1.55 × 10 -2 s -1, K 1 = 2.31 × 10 -7 mol dm -3, K 2 = 14.1×10 3 mol -1 dm 3 and K 3 = 6.31×10 3 mol dm -3 have been obtained at 30 °C and i = 0.1 mol dm -3. The thermodynamic activation parameters have been calculated. The experimental rate law is consistent with a mechanism in which the deprotonated [Cr III(Dpc)(Pro)(OH)] - is considered to be the most reactive species compared to its conjugate acid. It is assumed that electron transfer takes place via an inner-sphere mechanism.

    ABSTRACT: The kinetics and mechanism of the oxidation of trithionate (S 3O62-) and pentathionate (S5O 62-) ions by ferrate ions (FeO42-) were studied under pseudo first-order conditions. Trithionate was studied over the pH range 7.6 to 10.5 with initial concentrations in the range 1 to 12 mM, and pentathionate was studied over the pH range 7.7 to 9.0, with the same initial concentrations. In both cases the products were dithionate and Fe(III). Above a pH of 8.0 the proposed mechanism for trithionate involves reaction between protonated ferrate and trithionate as the rate-determining step with a rate constant of 2.9 M-1s-1. For pentathionate above a pH of 8.4, the proposed rate-determining step involves unprotonated ferrate, with a rate constant of 3.3M-1s-1. At lower pH values both thiosalts show a direct dependence on the hydrogen ion concentration, but increased hydrolysis complicates the interpretation.

    ABSTRACT: The kinetics of the ruthenium(III) catalysed oxidation of L-alanine by alkaline permanganate was studied spectrophotometrically using a rapid kinetic accessory. The reaction is first order with respect to [oxidant] and [catalyst] with an apparent less than unit order in [substrate] and [alkali] respectively. The results suggest the formation of a complex between the alanine and the hydroxylated species of ruthenium(III). The complex reacts further with the alkaline permanganate species in a rate-determining step, resulting in the formation of a free radical, which again reacts with the alkaline permanganate species in a subsequent fast step to yield the products. The reaction constants involved in the mechanism were calculated. There is a good agreement between observed and calculated rate constants under different experimental conditions. The activation parameters with respect to slow step of the mechanism were calculated and discussed.

    ABSTRACT: The kinetics of the interaction of glutathione (reduced) (GSH) with [Pt(en)(H2O)2](ClO4)2 and [Pt(dmen)(H2O)2](ClO4)2 (en = ethylenediamine, dmen = N,N′-dimethylethylenediamine) have been studied spectrophotometrically as a function of [substrate complex], [glutathione] and temperature at a particular pH (4.0). The reaction was found to proceed via rapid outersphere association complex formation followed by two slow consecutive steps. The first step involves the transformation of the outersphere complex into the innersphere complex containing Pt-S bond, while the second step involves chelation when the second aqua ligand is displaced. The association equlibrium constant (KE) and the two rate constants k1 and k2 have been evaluated. Activation parameters for both the steps have been calculated using Eyring equation. The low enthalpy of activation and large negative values of entropy of activation indicate an associative mode of activation for both steps.

    ABSTRACT: The kinetics of the title reaction have been investigated in both aqueous and micellar cetyltrimethylammonium bromide(CTAB) solutions. Rate data indicate that the reaction follows the template mechanism in both the media. The observed rate constant is affected by [CTAB] changes and the maximum rate enhancement is ca. 4 -fold. The following parameters have been calculated at pH 5.0: for aqueous, kobs = 5.6 × 10-5 s-1, ΔH# = 61 k J mol-1, ΔS# = -122 J K-1 mol-1; for CTAB, kψ = 24.7 × 10-5 s-1, ΔH# = 35 k J mol-1, ΔS# = -200 J K-1 mol-1, which reveal CTAB behaving as a catalyst. To explain the dependence of the reaction rate on [CTAB], pseudo-phase model proposed by Menger and Portnoy and modified by Bunton and Rodenas was used. The catalytic role of CTAB can be related to the extent of incorporation or association of the chromium(III)-tryptophan and ninhydrin into the micelles. Various factors which affect km, K S and KN are discussed taking into account the micellar surface solvent properties.

    ABSTRACT: Chromic acid oxidation of d (+)-xylose in water and in presence of surfactants has an induction period followed by autoacceleration. The kinetics and mechanism of the induction period have been studied spectrophotometrically in both media. Due to precipitate formation, the effect of cetyltrimethylammonium bromide (CTAB, cationic) cannot be studied whereas the oxidation rate increased with increase in sodium dodecyl sulphate (SDS, an-ionic) and octylphenoxypolyethoxy ethanol (TX-100, nonionic) concentration. Reaction is routed through the same mechanism as shown by the kinetic study in the absence and presence of surfactants. Micellar catalysis has been traced to partitioning of the chromic acid species and xylose between the aqueous and micellar pseudo-phases. Rate enhancement in SDS micelles is decreased by ammonium, lithium and sodium ions. Micellar binding/association constants and activation parameters were evaluated and discussed. A mechanism consistent with the results is proposed.

    ABSTRACT: The reaction of dichloro-{1-benzyl-2-(arylazo)imidazole}palladium(II), [Pd(R'aaiBz)Cl 2 ], where R'aaiBz= p -R'-C 6 H 4 -N=N-C 3 H 2 N 2 -1-CH 2 -C 6 H 5 ; R'=H (1), Me (2), Cl (3), with pyridine bases [RPy: R=H (a), 4-Me (b), 4-Cl (c), 2-Me (d), 2,6-Me 2 (e), 2,4,6-Me 3 (f)] has been studied spectrophotometrically in MeCN at 468 nm. The products (4) have been isolated and characterised as trans -Pd(RPy) 2 Cl 2 . The kinetics of the nucleophilic substitution has been examined under pseudo-first-order conditions at 298 K. The single phase reaction step has been observed for the bases HPy (a), 4-MePy (b) and 4-ClPy (c) and follows the rate law, rate= k [RPy] 2 [Pd(R'aaiBz)Cl 2 ]. The bases, 2-MePy (d), 2,6-Me 2 Py (e) and 2,4,6-Me 3 Py (f) exhibit bi-phasic reaction: rate-1= k ' [RPy][Pd(R'aaiBz)Cl 2 ] and rate-2= k " [RPy][Pd(R'aaiBz)Cl 2 ]. The rate data support nucleophilic association path. External addition of Cl m (LiCl) suppresses the rate, that follows the order; k / k '/ k " (3) > k / k '/ k " (1) > k / k '/ k " (2). The k 's are linearly related to Hammett † constants. The 2-MePy, 2,6-Me 2 Py and 2,4,6-Me 3 Py remarkably reduce the rate compared with 4-substituted pyridine bases. This is attributed to steric effect that destabilises the transition state. The rate decreases with increasing steric crowding at the ortho -position and follows the order: (d)>(f)>(e). The 4-substituted pyridine controls the rate via inductive effect and follows the order: (b)>(a)>(c).

    ABSTRACT: Reactions of methylating agents, MeI and Me 3 OBF 4 , with trans -Ir(CO)(Cl)(TPPTS) 2 (TPPTS=P( m -C 6 H 4 SO 3 Na) 3 ) are examined in H 2 O and DMSO. Three products are observed with MeI in water, Ir(CO)(Cl)(I)(Me)(TPPTS) 2 , Ir(CO)(Cl)(Me)(H 2 O)(TPPTS) 2 + and Ir(CO)(I)(Me)(H 2 O)(TPPTS) 2 + ; reactions in the presence of excess Cl m and I m form Ir(CO)(Cl) 2 (Me)(TPPTS) 2 and Ir(CO)(I) 2 (Me)(TPPTS) 2 , respectively. Reaction of trimethyloxonium + with trans -Ir(CO)(CI)(TPPTS) 2 produced only Ir(CO)(Cl)(Me)(H 2 O)(TPPTS) 2 + . None of the methyl compounds underwent hydrolysis or carbonylation.

    ABSTRACT: Base hydrolysis kinetics of chloropentaaminecobalt(III) complexes of a range of acyclic and cyclic pentaamine ligands, incorporating the rigid -NH-CH 2 -C(CH 3 )(NH 2 )-CH 2 -NH- motif, which must coordinate facially in octahedral complexes, are analysed in terms of ground state structural influences on hydrolysis rates. For complexes without experimental structural data, molecular mechanics was used to predict Co-Cl and Co-N bond distances. The computed strain energies and structural parameters both isomers ( trans and cis ) of all compounds are analysed. Although sterically crowded ligands, which should favour a five-coordinate intermediate, exhibit larger k OH values, only a modest correlation between ground state Co-L distances and hydrolysis rates is found. This suggests that the structures of the transition state and/or of the five-coordinate intermediate is important.

    ABSTRACT: The Lewis bases triphenyl phosphine and triethyl phosphite (L) displace C 60 from ( m 2 -C 60 )W(CO) 5 to produce the complexes ( m 1 -L)W(CO) 5 . These displacement reactions were studied under conditions where the concentrations of C 60 and L were at least 50 times the concentration of ( m 2 -C 60 )W(CO) 5 . The reactions in various solvents were first order with respect to ( m 2 -C 60 )W(CO) 5 . The pseudo first order rate constant values were independent of the concentration and of the nature of L but dependent on the coordinating ability of the solvent under conditions where [C 60 ]/[L] , 0. Under conditions where 0 h [C 60 ]/[L] h 1, the pseudo first order rate constant values decrease as the values of [C 60 ]/[L] increase. Two limiting cases of an interchange displacement of C 60 from ( m 2 -C 60 )W(CO) 5 , whose relative contributions to the overall mechanism depend on the nature of the solvent, are proposed to be a solvent-assisted C 60 -W(CO) 5 bond displacement and a dissociative displacement. The first step of the associative displacement pathway is a solvent-assisted dissociation of C 60 from ( m 2 -C 60 )W(CO) 5 producing the intermediate species (solv)W(CO) 5 , (solv=solvent), whereas the 16 electron unsaturated species W(CO) 5 is produced in the dissociative displacement pathway.

    ABSTRACT: Conventional and stopped-flow spectrophotometry was used to study the kinetics of ligand substitution in a number of mono g -diketone salen iron(III) complexes, [Fe(salen)(O 7 O)], by 8-hydroxyquinoline (=HO 7 N) in alcohol media (O 7 O m =anion of the g -diketones pentane-2,4-dione, 2,6-dimethylheptane-3,5-dione, 2,2,6,6-tetramethylheptane-3,5-dione, 1-phenylbutane-1,3-dione, 1,3-diphenylpropane-1,3-dione, and 1-(2-thienyl)-4,4,4-trifluorobutane-1,3-dione; salen=anion of N , N '-disalicylideneethylenediamine). As shown by spectrophotometry and conductometry, the solutions of complexes [Fe(salen)(O 7 O)] in alcohols ROH are subject to solvolytic dissociation, leading to neutral and charged solvento species [Fe(salen)S 2 ] (S=RO m and ROH, respectively). The dissociation constants K D for the systems [Fe(salen)(O 7 O)]/ROH, as determined by concentration-jump experiments as well as by dilution experiments, range from 3 2 10 m 5 M to 1 2 10 m 3 M. The reaction of complexes [Fe(salen)(O 7 O)] with HO 7 N in alcohols is biphasic, with first-order rate constant k 1 describing the initial solvolytic dissociation of [Fe(salen)(O 7 O)] (solvent assisted D-mechanism) and second-order rate constant k 2 , the consecutive reaction of the solvento species [Fe(salen)S 2 ] with HO 7 N to form [Fe(salen)(O 7 N)]. Depending on the nature of the coordinated g -diketone and solvent ROH, k 1 ranges from 0.12 to 31 s m 1 and k 2 from 1 2 10 3 to 26 2 10 3 M m 1 s m 1 at 298 K. Both the initial solvolysis step and the consecutive anation step involve a change in the coordination of the Salen ligand from non-planar to planar and vice versa .
