T. Kamikawa et T. Hayashi, PALLADIUM CATALYSTS FOR CROSS-COUPLING OF ORTHO-SUBSTITUTED ARYL TRIFLATES WITH GRIGNARD-REAGENTS, Synlett, (2), 1997, pp. 163
Dichloro (2-dimethylamino)propyldiphenylphosphine]palladium (PdCl2(ala
phos)) and hloro[1,3-bis(diphenylphosphino)-propane]palladium (PdCl2(d
ppp)) were found to be much more effective catalysts than PdCl2(PPh(3)
)(2) and other palladium complexes for cross-coupling of sterically co
ngested aryl triflates with aryl and alkynyl Grignard reagents.
