2,2′-Diamino-6,6′-dimethylbiphenyl as an efficient ligand in the palladium-catalyzed Suzuki-Miyaura and Mizoroki-Heck reactions

2,2'-Diamino-6,6'-dimethylbiphenyl was found to be an efficient ligand in the palladium-catalyzed Suzuki-Miyaura coupling reactions of aryl iodides. bromides, and chlorides and Mizoroki-Heck reactions of aryl iodides and bromides. Under appropriate conditions, all reactions gave the desired products in moderate to excellent yields. The ligand is inexpensive, air-stable and easy to available. (C) 2010 Elsevier Ltd.
