Chemical Communications (Chem Comm)
Chemical Communications is the leading journal for the publication of communications on important new developments in chemistry. All articles are short and publication is rapid, thus providing information on new avenues of research in the shortest possible time. A communication is usually followed up by a full paper in the corresponding section of Journal of the Chemical Society when fuller results of the work are known. Papers are drawn from most of the world's major areas of chemical research.

- [Show abstract] [Hide abstract] ABSTRACT: Highly chemoselective Friedel-Crafts acylation with twisted amides under mild conditions is reported for the first time. The reaction shows high functional group tolerance, obviating the need for preformed sensitive organometallic reagents and expensive transition metal catalysts. The high reactivity of amides is switched on by ground-state steric distortion to disrupt the amide bond nN → πCO* resonance as a critical design feature. Conceptually, this new acid-promoted mechanism of twisted amides provides direct access to bench-stable acylating reagents under mild, metal-free conditions.
- [Show abstract] [Hide abstract] ABSTRACT: Anatase TiO2 nanocrystals were crystallographically connected through UV-induced epitaxial attachments in 1D and 2D arrays with photocatalytic decomposition of the organic mediator.
- [Show abstract] [Hide abstract] ABSTRACT: Diverse and functionalized 2-hydroxybenzophenone derivatives were synthesized efficiently in good to excellent yield via the highly regioselective indium(iii)-catalyzed [2+2+2] benzannulation of 3-formylchromones with β-enamino esters or β-enamino ketones. This benzannulation reaction proceeds via a domino Michael/retro-Michael/6π-electrocyclization/deformylation reaction. In addition, 2-hydroxybenzophenones were also prepared by the indium(iii)-catalyzed [4+2] benzannulation reaction between 3-substituted chromen-4-ones and β-enamino esters or β-enamino ketones. Furthermore, the effects of substituents and π conjugation on the characteristics of the UV-Vis spectrum of synthesized 2-hydroxybenzophenones were examined. Compound 10s exhibited higher sun protection activity than oxybenzone which is used in most popular sunscreens.
- [Show abstract] [Hide abstract] ABSTRACT: Samarocene oxide [Cp*2Sm-O-SmCp*2] is mostly considered as an undesired decomposition product of the well-established but highly air-sensitive samarocene, [Cp*2Sm(thf)2]. [Cp*2Sm-O-SmCp*2] is often formed by accidental exposure of [Cp*2Sm(thf)2] to air or wet solvents. We show here that [Cp*2Sm-O-SmCp*2] acts as a mild oxide base and thus is a valuable synthetic equivalent for "O(2-)". The reaction of [Cp*2Sm-O-SmCp*2] with the inorganic and organic anhydrides COS, CS2, SO2, SO3, Re2O7, and (PhC(O))2O at room temperature resulted in each case in an O(2-) insertion. The corresponding products were isolated as their samarium complexes.
- [Show abstract] [Hide abstract] ABSTRACT: Correction for 'Regioselectivity in the Au-catalyzed hydration and hydroalkoxylation of alkynes' by Justin A. Goodwin et al., Chem. Commun., 2015, 51, 8730-8741.
- [Show abstract] [Hide abstract] ABSTRACT: The transition-metal-catalyzed direct triflation of naphthyl amides and naphthyl ketones has been accomplished for the first time. Benzophenone (BP) was found to be a suitable ligand for the cross-coupling reactions. Density functional theory (DFT) calculations revealed that excessive amounts of HOTf inhibit the reductive elimination of the C-F bond to realize the unusual reductive elimination of the C-OTf bond.
- [Show abstract] [Hide abstract] ABSTRACT: A highly efficient synthesis of benzoimidazo[1,2-a]imidazolone through a novel oxidative 5-exo-dig cyclization-ketonization cascade of 2-aminobenzimidazole, aldehyde and terminal alkyne has been explored under aerobic conditions. The reaction proceeds through copper-catalyzed addition of terminal alkynes to imines derived from 2-aminobenzimidazole with aldehyde followed by intramolecular cyclization. The atmospheric molecular oxygen acts as an oxygen source for the newly formed carbonyl group in the final product.
- [Show abstract] [Hide abstract] ABSTRACT: The potential of NMR crystallography to verify molecular crystal structures deposited in structural databases is evaluated, with two structures of the pharmaceutical furosemide serving as examples. While the structures differ in the placement of one H atom, using this approach, we verify one of the structures in the Cambridge Structural Database using quantitative tools, while establishing that the other structure does not meet the verification criteria.
- [Show abstract] [Hide abstract] ABSTRACT: The dipyrrin-1,9-dione scaffold of heme metabolite propendyopent coordinates late transition metals (Co, Ni, Cu, and Zn) forming homoleptic, pseudo-tetrahedral complexes. Electrochemical and spectroscopic studies reveal that the monoanionic, bidentate ligands behave as electron reservoirs as the complexes reversibly host one or two ligand-based radicals.
- [Show abstract] [Hide abstract] ABSTRACT: Four brand new hybrid ligands combining an N-heterocyclic carbene tethered with two isomeric nido-dicarbaundecaborane dianions, a neutral closo-dicarbadodecaborane or a closo-dicarbadodecaborane anion are described. Versatile coordination of the ligands to Rh(I) is demonstrated, in which both NHC and carborane moieties covalently coordinate a metal centre.
- [Show abstract] [Hide abstract] ABSTRACT: We demonstrate herein a facile approach for constructing -C[double bond, length as m-dash]N- linked COFs from acetals. Three new COFs (imine-linked , hydrazone-linked , and azine-linked ) were synthesized by the direct condensation of dimethyl acetals and amines. All the synthesized COFs are highly crystalline and exhibit good thermal stability.
- [Show abstract] [Hide abstract] ABSTRACT: A method for the phototriggered release of a biogenic amine from the host-guest complex with the cucurbituril macrocycle in aqueous solution was devised. The approach exploits a photoinduced pH jump from 8 to 5, combined with the pH-dependent switching of the competitive capacity of a guest dye. The fluorescence fingerprint of the competitor can be used to monitor the amine release in the micromolar concentration regime.
- [Show abstract] [Hide abstract] ABSTRACT: The quantification of metabolites is essential for understanding and improving biological systems. With the aim to quantify in one map a complex mixture composed of low concentrated metabolites, a new experiment called the (1)H-(13)C QUIPU HSQC allows improving of both resolution and sensitivity for investigation of vegetal extracts.
- [Show abstract] [Hide abstract] ABSTRACT: A novel strategy to construct photocontrolled protein nanowires with reversible morphology was reported through photoisomerizable azobenzene-cored dendrimer evoked protein self-assembly. Furthermore, the curvature of the protein nanowires could be switched by alternatively irradiating with visible light and ultraviolet light.
- [Show abstract] [Hide abstract] ABSTRACT: Compartmentalised structures based on droplet interface bilayers (DIBs), including multisomes and compartmentalised vesicles, are seen by many as the next generation of biomimetic soft matter devices. Herein, we outline a microfluidic approach for the construction of miniaturised multisomes of pL volumes in high-throughput and demonstrate their potential as vehicles for in situ chemical synthesis.
- [Show abstract] [Hide abstract] ABSTRACT: We report chemo- and regioselective direct reductive deoxygenation of 1-en-4-yn-3-ols into 1,4-enynes through FeF3 and TfOH cooperative catalysis under NBSH-mediated conditions. Further, we show the efficient synthesis of a pharmaceutically significant 1,4-enyne. The present methodology can also be used for chemo- and regioselective direct deoxygenation of other alcohols.
- [Show abstract] [Hide abstract] ABSTRACT: This communication reports a new nanocatalytic scheme based on the facts that the redox reaction between a highly outer-sphere-reaction-philic (OSR-philic) species and a highly inner-sphere-reaction-philic (ISR-philic) species is slow and that an OSR- and ISR-philic Au-nanocatalyst label can mediate the two different types of redox species. This scheme allows highly sensitive and incubation free detection of creatine kinase-MB.
- [Show abstract] [Hide abstract] ABSTRACT: Low molecular weight hydrogels, prepared from glycosyl-nucleoside-lipid amphiphiles, exhibit shear-thinning behaviour and reversible thermally- and mechanically-triggered sol-gel transitions. Using mechanical shear stimulation, the release of entrapped anti-TNFα increases and the released anti-TNFα demonstrates efficacy in in vitro neutralization bioassays. Delivery of anti-TNFα is of general interest and broad medicinal utility for treating autoimmune diseases such as rheumatoid arthritis.
