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 1H, 31P and 15N-1H-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.

Reaction of optically active cyclic allylsilanes, (S)-3-(trimethylsilyl)cyclopentene and -cyclohexene, wich were prepared by palladium-catalyzed asymmetric hydrosilylation of cyclic dienes, with ethylene oxide in the presence of titanium chloride proceeded with anti stereochemistry to give (R)-3-(2-hydroxyethyl)cyclopentene and -cyclohexene, respectively.
