these ligands were less explored relatively for carbene involved reactions owing to the formation of carbene-phosphine ylides. In this report we successfully used three different phosphine stabilized Cu(I) complexes (1–3) as catalysts for chemoselective carbene insertion into the N–H bond of different aromatic amines over the formation of olefin (carbene dimerized product). In order to understand the

bond formation in recent years. However, the existing methods suffer from unstable starting materials, expensive metal catalysts and organic solvents. Herein, insertion of sulfoxonium ylides into arylamines under metal-free conditions has been developed. The method employs water as solvent at mild temperature and is amenable to the late-stage modification of structurally complex bioactive compounds
