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.
