Sc(OTf)(3) catalyzed electrophilic amination of arenes: An expeditious synthesis of aryl hydrazides
Arenes react smoothly with diethyl azodicarboxylate in the presence of a catalytic amount of scandium triflate in dichloromethane at ambient temperature to afford the corresponding aryl hydrazides in high yields with high regioselectivity.
