Abstract

N-Acyl dimesylamines RC(O)N(SO2CH3)2 (3) have been prepared by reacting solid KN(SO2CH3)2 with neat liquid RC(O)Cl at 70-90 °C [R = C2H5, (CH3)2CH, (CH3)3C-CH2 , CH2Cl, CHCl2] or solutions of AgN(SO2CH3)2 in methyl cyanide with RC(O)Cl at room temperature [R = (CH3)3C, CH2Cl, CHCl2, CCl3 , C6H5 , CH2=CH]. Addition of chlorine or bromine to 3 (R = CH2 = CH) affords the corresponding compounds 3 with R = CH2Cl-CHCl and CH2Br-CHBr, respectively. By hydrolysis of 3 (R = CCl3), CCl3C(O)NHSO2CH3 (5) is obtained. The new compounds 3 and 5 are characterized by spectroscopic (NMR, MS) and analytical methods.
