Article
The stereoselective activation of alkanes constitutes a long-standing and grand challenge for chemistry. Although metal-containing enzymes oxidize alkanes with remarkable ease and selectivity, chemical approaches have largely been limited to transition metal–based catalytic carbon–hydrogen functionalizations. Alkanes can be protonated to form penta...

N,N′‐Diboryl‐4,4′‐bipyridinylidene (BBiPy) has been utilized in sub‐stoichiometric amounts along with anionic base as one electron donor species for both transition metal‐free borylation of aryl halides and arene C−H functionalization with aryl iodides for biaryl syntheses. Reaction between BBiPy and potassium tert‐butoxide or methoxide has led to...

The intramolecularly double‐donor‐stabilized stannylene 1 has been synthesized from the salt‐metathesis reaction between two equivalents of lithium pyridine ene‐amide L1 and SnCl2. Compound 1 exhibits dipolar behavior when reacted with B(C6F5)3 leading to the zwitterionic compound 2. The reaction of 1 with one equivalent and 0.5 equivalent of AgOTf...
Article
The compliance of three acyclic flexible ligands of the type N2X2 with CH2CH2 linker in the backbone: diiminodi(furan) L1, diiminodi(thiophene) L2 and diiminodiphosphine L3 have been employed for the coordination of chlorogermyliumylidene and gold(I) chloride units. The chlorogermyliumylidenes have been stabilized by the two imino nitrogen coordina...
Article
The adaptability of three acyclic tetradentate ligands with –CHR-CHR- (R = H or alkyl substituent) linker in the backbone: bis(alpha-iminopyridine) L1 and the reduced form L2 and diaminodiphosphine L3 to stabilize various stannylenes have been explored. The reaction of L1 with two equivalents of Sn[N(SiMe3)2]2 led to the stabilization of a bisstann...
Article
The diiminodiphosphine (Lim) and diaminodiphosphine (L-NH and L-NMe) with bifunctional PNNP ligand framework have been employed to host two [GeCl]+ units leading to the formation of bis(chlorogermyliumylidene) 1-3 respectively. The synthetic route involves 1:2 stoichiometric reaction between PNNP ligand and GeCl2.dioxane and subsequent addition of...
Article
An acyclic flexible bis(α-iminopyridine) ligand has been employed for the stabilization of chlorostannyliumylidene and a tin(II) dication. The syntheses involve the abstraction of chloride from the tin dichloride precursor using trimethylsilyl trifluoromethane sulfonate. The apically disposed tin(II) dication exhibits electrophilic behaviour and un...
Article
Bis(chlorogermyliumylidene) 2 has been strategically obtained within redox-active bis(alpha-iminopyridine). Metal-free reduction of 2 followed by protonation led to elusive 2,3-di(pyridin-2-yl)piperazine with meso-stereoselectivity. Formation of persistent triplet diradical upon reduction and...

Syntheses of heavier Group 14 analogues of “Arduengo-type” N-heterocyclic carbene majorly involved the use of conventional alkali metal-based reducing agents under harsh reaction conditions. The accompanied reductant-derived metal salts and chances of over-reduced impurities often led to isolation difficulties in this multi-step process. In order t...
Article
The germanium(ii) center of dicationic compound 1 donates an electron pair to transition metal Ag(i) and Au(i) cations, leading to complexes 2 and 3 respectively. Complex 3 is stabilized by [Ge:](2+)→Au(i) σ-donation and π-back donation from filled d-orbitals of Au(i) to the two sets of p-orbitals available on Ge(ii) centers.
Article
Deoxygenation of fatty acids (oleic and stearic acids) and non-edible oil (Jatropha oil) over Pd(1 - 5 wt%) supported on two structurally different, three-dimensional, mesoporous silica (SBA-12 and SBA-16) catalysts was investigated. Pd/SBA-16 (cubic mesoporous structure with space group Im m) showed higher catalytic activity than Pd/SBA-12 (hexago...

Fatty monoester lubricant base oils as high as 96.7 mol% were prepared by reacting methyl oleate with long-chain alcohols viz., 2-ethyl-1-hexanol (C 8-OH), 1-decanol (C10OH) and 1-dodecanol (C 12OH) in the presence of a solid Fe-Zn double-metal cyanide (DMC) complex catalyst. Unlike many other acid catalysts, DMC doesn't produce undesired ether sid...
