One-step synthesis of mixed carboxylate sulphonate esters of diols

Abstract

Reaction between 1,2- or 1,3-diols, sulphonic acids and carboxylic acid derivatives leads directly to mixed carboxylate sulphonate esters. The process is believed to involve 1,3-dioxolan-2-yl cation or 1,3-dioxan- 2-yl cation intermediates.
