Diaminosulfoxonium salts were prepared by alkylation of sulfonimidamides. Their physical properties were described. Their reaction with bases gave the corresponding ylides and sulfonimidamides. The intramolecular rearrangement of the ylides led to ortho substitution via intermediate cyclohexadienimines. Hydrogen transfer, accompanying rearomatization and the subsequent action of bases gave dihydro-2,1-benzisothiazole derivatives. These ylides were also found to react with aldehydes to afford epoxides in moderate yields.
通过磺酰亚胺的烷基化制备了二氨基磺鎓盐。对它们的物理性质进行了描述。它们与碱反应生成相应的酰化物和磺酰亚胺。酰化物的分子内重排导致通过中间环己二烯亚胺进行正交取代。氢转移、伴随的重气化和随后的碱作用产生了二氢-2,1-苯并异噻唑衍生物。研究还发现,这些酰化物还能与醛发生反应,以中等产率生成环氧化物。
