Ligand-Promoted Rh(III)-Catalyzed Coupling of Aryl C–H Bonds with Arylboron Reagents

Rhodium­(III)-catalyzed C–H arylation of arenes with phenylboronic acid pinacol esters has been achieved using a readily removable N-pentafluorophenylbenzamide directing group for the first time. The use of a bidentate phosphine ligand (Binap) significantly increased the yield of the cross-coupling of C–H bonds with organoboron reagents.
