Abstract

Bifunctionalized sulfonium ylides – sulfonium acyl sulfonylmethylides – were directly and efficiently prepared from various acetylenic sulfones and aliphatic sulfoxides under heating conditions. The current method features short reaction time, low cost, readily available starting materials, convenient operation, and purification, providing an efficient access to widely applied bifunctionalized sulfonium ylides.
