THERE has recently been widespread interest in the properties of dimethyl sulphoxide (DMSO), as a chemical and a solvent, in both organic1 and inorganic2–4 systems. Its chemical behaviour is particularly influenced by its nucleophilic or donor character, which is potentially of two types, since either the sulphur or the oxygen atom should be capable of forming dative bonds to suitable electrophilic groups. This dual behaviour in organic systems has been discussed and exploited by Smith and Winstein5. The existence of the s-methylsulphoxonium ion has since been conclusively demonstrated by X-ray study6.
