Normal C2-5 amine hydrochlorides were treated with excess SO2Cl2 18 hrs. on a water bath at 75°. In some cases more SO2Cl2 was added. The resulting oil was treated with dry ether, the precipitated amine hydrochloride filtered off, and the filtrate distilled in vacuo to give monoalkylsulfamyl chlorides, RNHSO2Cl (I). [RNH2.HCl (R given), amount added, and recovered (g.), volume (ml.) SO2Cl2 used, % yield of corresponding I (based on RNH2.HCl used) and b.p. (redistilled samples) given]: Et, 52, 23, 105 (a further 100 ml. was added after 4 hrs. reflux), 42, b0.05 52; Pr, 52, 26, 350, 13, b0.2 78°; Bu, 77, 27, 450, 39, b0.11 80°; and Am, 19, 12, 150, 8, b0.15 95°. When HCl salts of methyl-, hexyl-, cyclohexyl-, and octylamine were used, the yields of the corresponding I were too low to permit their isolation. That at least MeNHSO2Cl was formed could be concluded from the fact that MeNHSO2NHPr, m. 57-8° (ether-petr. ether), could be obtained when the impure product was treated with PrNH2. EtNHSO2NHBu, m. 73-5° (hexane), was similarly obtained from EtNHSO2Cl.
