For the preparation of S-vinylsulfilimines (1), mainly S-phenyl-N-tosyl-S-vinylsulfilimine, three routes were examined, viz., (A) the reaction of vinyl sulfide with chloramine T, (B) that of 2-haloethyl phenyl sulfide with chloramine T followed by dehydrohalogenation, and (C) that of 2-hydroxyethyl sulfide with chloramine T followed by acetylation of the hydroxyl group and deacetoxylation. Route A has disadvantages of troublesome preparation of vinyl sulfides and low yield. Route B gives the precursor sulfilimine to 1 in good yield only by use of anhydrous chloramine T. Route C gives the best results in view of starting material and yield.
为制备 S-乙烯基亚磺酰亚胺(1),主要是 S-苯基-N-对甲苯磺酰-S-乙烯基亚磺酰亚胺,研究了三条路线,即(A)乙烯基硫醚与氯胺 T 反应,(B)2-卤乙基苯硫醚与氯胺 T 反应,随后进行脱卤化氢,以及(C)2-羟乙基硫醚与氯胺 T 反应,随后对羟基进行乙酰化处理,并脱乙酸。路线 A 存在制备乙烯基硫醚麻烦且产率低的缺点。路线 B 只有在使用无水氯胺 T 的情况下,才能以良好产率得到1的前体亚磺酰亚胺。从起始材料和产率来看,路线 C 效果最佳。
