Abstract

Abstract: The reaction of 1, 3-dithiolanes with n-butyllithium results in fragmentation to the corresponding thiocarbonyl compound followed by further reaction with n-butyllithium. All four types of thiocarbonyl reactions are observed: reduction, S-addition, C-addition, double addition. Synthetic applications of this reaction for the synthesis of secondary mercaptans and 1, 2-carbonyl transposition (23-, 24a-c) are described.
