摘要
The N-methyl bis-imidazolium salts 3 were converted to the silver carbenes 7, then reacted to give palladium(II) complexes 4 with trans-chelating, bidentate bis-imidazolylidine ligands. The similar salts 8, that do not have N-methyl substituents, gave the tetradentate complexes 9 in direct reactions with palladium chloride. The potential of these complexes for asymmetric catalysis is discussed. (C) 2002 Published by Elsevier Science Ltd.
