Achieving site-selective C-H functionalization of arene is a fundamental challenge, as it is mainly controlled by the electronic nature of the molecules. A chelation-assisted C-H functionalization strategy overcomes the selectivity issues by utilizin

We report a method to produce amido esters and amido phosphonates. Octacarbonyldicobalt [Co2(CO)8] was found to be an efficient nongaseous CO source that could be used as a reagent for the carbonylation of diazo esters and diazo phosphonates under mi

Distal C-H bond functionalization of heterocycles remained extremely challenging with covalently attached directing groups (DG). Lack of proper site for DG attachment and inherent catalyst poisoning by heterocycles demand alternate routes for site se

Phosphine ligands have been successfully used along with Cu(I) for several catalytic reactions, nevertheless these ligands were less explored relatively for carbene involved reactions owing to the formation of carbene-phosphine ylides. In this report

Phosphine-coordinated air-stable Cu(I) catalyst (1) has been synthesized and characterized. Catalyst 1 is found to be active toward highly chemoselective carbene insertion into the N-H bond over the O-H bond and also over the formation of olefins whe

The chemistry of A and D/A carbenes (D and A are donor and acceptor groups, respectively) is known to a great extent in the literature. Nevertheless the chemistry of the A/A class of carbenes is less explored, although the A/A class of carbenes is mo
