The reactions of the sulfoxides and sulfones of sulfur mustard and an analogue, 2-chloroethyl ethyl sulfide, with hydroxide ion in aqueous solution at 25° have been studied. In contrast with the behaviour of the parent sulfides, for which exclusive substitution of chlorine is observed under comparable conditions, the oxidized compounds react through base-catalysed elimination of HCl to give the corresponding alkenes. Second-order rate constants for these reactions are reported and implications for the metabolism of sulfur mustard are discussed.
我们研究了硫芥的硫醚和砜以及类似物 2-氯乙基硫醚在 25° 的水溶液中与氢氧根离子的反应。与母体硫化物在类似条件下发生氯完全取代的行为不同,氧化化合物通过碱催化消除 HCl 发生反应,生成相应的烯。报告了这些反应的二阶速率常数,并讨论了对硫芥新陈代谢的影响。
