Optically pure alpha-silylphosphetanes have been prepared through stereoselective metallation-silylation reactions of the P-menthylphosphetane oxide 1. Bridging of two phosphetane units by means of bifunctional chlorosilanes leads to various bidentate ligands and, particularly, to the chiral, trans-chelating diphosphine 6b. Its square planar rhodium complex trans-Rh(CO)Cl(6b) has been structurally characterized.
