Abstract
Abstract Dithioacetals and ketals are useful synthetic intermediates.1 In general, they are obtained by the acidcatalysed addition of thiol to carbonyl compounds.2 The reaction is however a reversible one, and an excess of thiol together with continuous removal of water are often required for optimum yield. Recently, it was reported3 that methylthiotrimethylsilane converted carbonyl compounds to dithioacetals and ketals. The reaction however can not be applied to other thiols.
