A number of heterocyclic sulphur compounds and their sulphoxides have been S- and O-alkylated respectively, with silver perchlorate and alkyl halides. 5-Methoxydibenzothiophenium and 10-methoxyphenoxathiinium perchlorates reacted with amines to give 5- and 10-aminosulphonium salts, respectively, and with certain carbanions to give zwitterionic compounds.
