S,S-Dialkyl Dithiocarbonates as a Convenient Source of Alkanethiols: an Improved Synthesis of Alkylthiocarboxylic Acids

A wide variety of β-alkylthiocarboxylic acids are obtained by addition of alkanethiols - generated in situ from S,S-dialkyl dithiocarbonates - to appropriate α,β-unsaturated carboxylic acids in good to excellent yields.
