摘要：

The novel PCP chiral ligand R,R-{C6H4-2,6-(CH2P*PhBut)(2)} and its platinum metal complexes have been easily synthesized in enantiomeric pure form. The palladium compound R,R-PdCl{C6H3-2,6-(CH2P*PhBut)(2)} has been characterized by X-ray crystal structure analysis thus confirming the absolute configuration of the complexated ligand. Preliminary catalytic experiments with the iridium and palladium complexes R,R-IrH4{C6H3-2,6-(CH2P*PhBut)(2)} and R,R-PdCl{C6H3-2,6-(CH2P*PhBut)(2)} in the dehydrogenation of cycloalkanes and in the hydrosilylation of styrene, allylic alkylation and Heck coupling reactions, respectively have been carried out.
