摘要：

Novel rhodium(I) and ruthenium(II) complexes with the chiral cyclopentadienylphosphine bidentate ligand PPFCp have been prepared and characterized crystallographically. The cationic rutheniumvinylidene complex [Ru(CCHPh)(PPh)(PPFCp)]PF, obtained from [RuCl(PPh)(PPFCp)] and phenylacetylene, reacts with 1-buten-3-ol to afford 3-methyl-1-phenyl-4-penten-2-one in moderate yield with moderate enantioselectivity.
