The title α- and N-halosulfoximides 1-4 undergo base-induced rearrangement reactions to give the same N-sulfinylimines 5, suggesting that these rearrangements all involve the intermediacy of a cyclic sulfoximide, a thiazirine S-oxide 14, which has a novel three-membered ring system with an endocyclic S=N group.
标题中的α-和N-卤代亚磺酰亚胺1-4经过碱诱导的重排反应,得到了相同的N-亚磺酰亚胺5,这表明这些重排反应都涉及到环状亚磺酰亚胺的中间产物--噻嗪S-氧化物14,该环状亚磺酰亚胺具有新颖的三元环系统,带有一个内环S=N基团。
