摘要：

The (4R,5R)-4,5-Bis(diphenylphosphinomethyl)-2-(alpha-naphthoxy)-1,3,2-dioxaphospholane (1) and (4R,5R)-4,5-bis(diphenylphosphinomethyl)-2-dimethylamino-2-oxo-1,3,2-dioxaphospholane (2), analogues of the chiral bisphosphine ligand DIOP, have been synthesized. Both compounds have a second phosphorus functionality in the backbone of the chiral bisphosphine. That the reactivities of the various phosphorus atoms in 1 are different was shown for the reaction with BH3. The complexation behaviour of 1 towards Rh(I) was studied with the aid of P-31 NMR spectroscopy.
