Ruthenium Catalyzed Ortho‐Arylation Reaction of Benzoic Acids with Arylthianthrenium Salts
Angewandte Chemie International Edition, EarlyView.A catalytic ortho‐arylation method has been developed to convert arylthianthrenium salts into carboxylate‐functionalized biaryls, which can be removed in situ or used for further derivatization. This reaction is broadly applicable to (hetero)arenecarboxylic acids, with excellent functional group compatibility and orthogonality to cross‐couplings ...

Angewandte Chemie International Edition, Accepted Article.Catalytic asymmetric 1,3‐dipolar cycloadditions (1,3‐DCA) using iminoesters as ylide precursors offer a powerful approach to accessing stereochemically complex, biologically relevant pyrrolidines. While previous studies have already achieved impressive stereoselectivities, catalytic productivity remains a challenge, with turnover numbers (TON ...

Chromogenic azole diazothiacrown ethers [PDF]
Supramolecular Chemistry, 2008 Azocrown ethers with sulfur atoms and pyrrole or imidazole residue as a part of macrocycle have been synthesized. Their metal complexation abilities in acetonitrile were studied using UV-vis spectrophotometry. The largest spectral changes were observed for both pyrrole- and imidazole azothiacrown ethers on complexation with Pb2+, Cu2+, Zn2+, Ni2+, Co2+

Advances in Metal‐Free Transamidation: A Sustainable Approach to Amide Bond Formation
Chemistry – An Asian Journal, EarlyView.This review highlights the recent developments of transamidation reactions under metal‐free reaction conditions. Various amines including weak nucleophilic amines such as aromatic amines have been used to achieve the transamidation reactions under mild and relatively green reaction conditions. Abstract The amide functionalities are a crucial functional
