摘要

The complex [(CF3-BINAP(O))Rh(COD)][ClO4]·Et2O (2, CFa-BINAP(O) = 2- {bis[3,5-bis(trifluoromethyl)phenyl]phosphino } -2 '- {bis [3,5-bis(trifluoromethyl)phenyl]phosphinyl } -1,1、-binaphthyl, COD = 1,5-cyclooctadiene) was obtained directly from the reaction of CF3- BINAP(O) ligand with [Rh(COD)][C104]. Complex 2 has been characterized by single-crystal X-ray diffraction. The crystal adopts space group P21/n with a = 19.0727(4), b = 15.6275(4), c = 22.3039(6) A, fl = 112.3570(10)°, V= 6148.2(3) A3, Z = 4, Dc = 1.693 g/cm3, F(000) = 3144, μ(MoKa) = 0.500 mm-1, the final R = 0.0947 and wR = 0.2501. Structural studies reveal that Rh(I) is coordinated by one oxygen and one phosphorus in the same ligand. Asymmetric hydrogenation of acetami- docinnamic acid with compound 2 was also evaluated.
