Concise Synthesis of Pyridyl Sulfides. Direct Nucleophilic Displacement of Haloheteroaromatics by Mercaptan Promoted by K-Selectride.

Abstract A simple and efficient synthetic method for sulfides from halogenated heteroaromatic compounds is described. An alkylthioborate, generated from K-Selectride and a thiol, rapidly reacted with various haloheteroaromatics under mild conditions.
