Mono-Cr(CO)3 complexes of biphenyl compounds: Cross-coupling reactions of (η6-arene)chromium complexes with arylmetals

Cross-coupling reaction of tricarbonyl(η6-halobenzene)chromium complexes with arylmetals in the presence of palladium(0) catalyst produced mono-Cr(CO)3 complexes of biphenyl compounds in good yield. Reaction of tricarbonyl(2,6-substituted 1-halobenzene)chromium complexes with ortho-substituted phenylboric acid gave stereoselectively cross-coupling products.
