摘要：

A simple method for preparation of CH3PF2 from CH3PCl2 is reported. The phosphonium salts CH3PF2H+MF6- are obtained by the reaction of CH3PCl2 with superacidic systems HF/MF5 (M = As, Sb). CH3PF2H+SbF6- crystallizes in the space group P1BAR with a = 548.4(4)pm, b = 695.5(8)pm, c = 960.2(9) pm, a = 94.68(5)degrees, beta = 97.19(6)degrees, gamma = 94.41(6)degrees and Z = 2. CH3PF2H+SbF6- crystallizes in P1BAR with a = 554.3(3), b = 724.2(4), c = 970.4(5), alpha = 94.73(4)degrees, beta = 96.14(5)degrees, gamma = 95.30(4)degrees.
