The first Suzuki− Miyaura cross-coupling reactions of the synthetically versatile aryl O- carbamate and O-sulfamate groups are described. The transformations utilize the inexpensive, bench-stable catalyst NiCl2 (PCy3) 2 to furnish biaryls in good to excellent yields. A broad scope for this methodology has been demonstrated. Substrates with electron- donating and electron-withdrawing groups are tolerated, in addition to those that possess ...
