N-Chloro-dimesylamine ClN(SO2Me)2 (1) reacts with the appropriate triorganophosphines to give the ionic chloro(triorgano)phosphonium dimesylamides R3PCl(1+)*N(SO2Me)2(1-) .The reaction of 1 with (MeO)3P affords (MeO)2P(O)Cl and MeN(SO2Me)2; its reaction with (PhO)3P or PCl3 leads to elimination of MeSO2Cl and formation of the phosphine imides Y3P=NSO2Me .The (1/1) dichloromethane solvate of 2a crystallizes in the monoclinic space group P21/c with a = 1735.6(7), b = 841.1(4), c = 1658.4(7) pm, β = 118.34(3) deg, U = 2.1309(16)nm3, Z = 4.The crystal lattice consists of discrete iPr3PCl(1+) cations (P-Cl 199.4 pm, bond angles at P 105.7-117.5 deg), (MeSO2)2N(1-) anions and CH2Cl2 molecules apparently hydrogen-bonded to oxygen atoms of the anions. 3a crystallizes in the monoclinic space group P21/c with a = 974.7(3), b = 2052.3(6), c = 959.5(3) pm, β = 98.820(14) deg, U = 1.8967(10) nm3, Z = 4.The dimensions of the molecule (P-N 154.4, N-S 159.8 pm, P-N-S 126.2 deg) are consistent with a delocalized electronic structure in the P-N-S system. Key words: N-Chloro-dimesylamine; triorganophsphines; triorganophosphites; phosphorus trichloride; chloro(triorgan)phosphonium dimesylamides; N-mesyl phosphine imides; X-ray structures:
