[Structure: see text] Various alkenes were prepared from phenyl sulfides in a one-pot manner at room temperature by converting them to the corresponding S-aminosulfonium salts with O-mesitylenesulfonylhydroxylamine, followed by treatment with potassium carbonate. Alkenes were formed by cis-elimination of in situ generated phenyl sulfilimines.
[结构:见正文]在室温下,通过一锅法由苯基硫化物制备各种烯烃,方法是将它们用O-亚甲基磺酰基磺酰羟胺转化为相应的S-氨基s盐,然后用碳酸钾处理。通过顺式消除原位生成的苯基亚硫亚胺形成烯烃。
