Abstract
Palladium complexes derived from inexpensive dppf ligand catalyze the cross-coupling reaction of alkenyl bromides with thiols under low catalyst loading. These reactions occur in high yields and display wide scope, including the coupling of bulky thiols and trisubstituted bromoolefins, and functional group tolerance. In addition, a thioetherification of less reactive chloroalkenes and alkenyl tosylates has also been achieved.
