Ab initio molecular orbital theory has been used to investigate a series of possible chlorosulfonium ylides to assess the potential for ylide intermediacy in the chlorination of organic sulfides. The majority of optimized structures are best viewed as thionium salts. Only ylide structures in which the putative carbanionic centre bears a powerful anion stabilizer (e.g. cyano or carbomethoxy) survive optimization.
