Abstract

There are now a number of efficient experimental procedures available for palladium-and nickel-catalyzed cross-coupling reactions of aromatic organometallic reagents with aryl halides.[1, 2] However, the high cost of palladium and the required phosphine ligands, as well as the high toxicity of nickel catalysts, led us to explore the use of alternative metals for such coupling reactions. Following the pioneering work of Kochi and co-workers and ...
