摘要：

The title compound (MeSO2)2N-SO2-NCO (1) is obtained from Cl-SO2-NCO and AgN(SO2Me)2 in benzene. It is instantaneously and completely hydrolyzed by excess water to form CO2, NH4+, SO42- and (MeSO2)2N-. The addition of alcohols to the isocyanate function of 1 leads to N-substituted urethanes (MeSO2)2N-SO2-NH-C(O)OR with R = Me, Et or (i)Pr. 1 crystallizes in the triclinic space group P1BAR with a = 532,4(3), b = 747,8(5), c = 1259,6(6) pm, alpha = 79,90(5), beta = 86,30(5), gamma = 77,49(5)-degrees, V = 0,4818(3) nm3 (at - 95-degrees-C), Z = 2. The bonding parameters and the conformational properties of the molecule are discussed and compared with those of the known electron-diffraction structure of Cl-SO2-NCO in the vapour phase.
