NiCl2(PCy3)2:  A Simple and Efficient Catalyst Precursor for the Suzuki Cross-Coupling of Aryl Tosylates and Arylboronic Acids

NiCl(2)(PCy(3))(2) associated with PCy(3) promotes the selective cross-coupling of aryltosylates with arylboronic acids under relatively mild reaction conditions, and a variety of functional groups are tolerated in both arenes. This is one of the simplest and most efficient experimental procedures for the coupling of arylboronic acids with aryl tosylates reported to date. Reaction: see text.
