Chemoselective Carbene insertion into the N–H Bond over O–H Bond Using a Well-Defined Single Site (P–P)Cu(I) Catalyst

Phosphine-coordinated air-stable Cu­(I) catalyst (<b>1</b>) has been synthesized and characterized. Catalyst <b>1</b> 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 when numerous aminophenols were treated with a variety of α-aryl diazoesters under normal experimental conditions
