摘要：

Optically active ligands 2 and 3 were synthesised from phenylglycine and the coordination of ligand 2 to PdCl2(CH3CN)(2) and PtCl2(C6H5CN)(2) was studied with H-1, P-31 and N-15-H-1-HMQC NMR spectroscopy. The results indicated P,O rather than P,N bidentate coordination. Both ligands were tested in the palladium catalysed hydrosilylation of cyclic 1,3-dienes. Asymmetric induction of up to 84% (25% yield), which is the hitherto highest reported ee value for asymmetric hydrosilylation of 1,3-dienes, was achieved as measured on the allylic alcohols formed after ethanolysis-oxidation of the initially formed allylic silanes.
