Copper Corrole as an Efficient Catalyst for Esterification of Allylic sp³-C-H Bonds with Carboxylic Acids

Copper 5,10,15-tris(pentafluorophenyl)corrole (CuTPFC) catalyzed oxidative cross dehydrogenative coupling (CDC) of allylic sp(3)-C-H bonds and acids had been investigated in a homogeneous system, which provided allylic esters smoothly. This reaction proceeded with broad substrate scope and good functional group tolerance. In a gram scale test, the turnover number (TON) reached 5100 at only 0.01 mol% catalyst loading, indicating the current catalytic system has potential uses in the allylic esters.
