Abstract

Novel rhodium(I) and ruthenium(II) complexes with the chiral cyclopentadienyl−phosphine bidentate ligand PPFCp have been prepared and characterized crystallographically. The cationic ruthenium−vinylidene complex [Ru(CCHPh)(PPh3)(PPFCp)]PF6, obtained from [RuCl(PPh3)(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.
