Synthesis of dialkyl sulphites from alcohols in the halogen–pyridine–sulphur dioxide system. Novel behaviour of alkyl chlorosulphates in the pyridine–sulphur dioxide system
Abstract
Dialkyl sulphites are formed selectively from alcohols in the halogen–pyridine–sulphur dioxide system. The behaviour of alkyl chlorosulphates in the pyridine–sulphur dioxide system has been investigated and the role of halogenosulphinate ion in this reaction is discussed.
