Abstract Water as a cosolvent has significant improving effect on the reductivity of SmI2 in the reduction of sodium alkyl thiosulfates and alkyl thiocyanates. A new method for synthesis of alkyl thiols by SmI2/THF/H2O system has been developed.

Disulfides were obtained by the reaction of thiocyanates with equivalent SmI2. Smarium thiolates were generated by the reaction of an equivalent of thiocyanates with two equivalents of SmI2, and then reacted smoothly with acyl chlorides to give thiolesters.
In this paper we report an efficient and mild procedure for the conversion of organic thiocyanates to thiols in the presence of phosphoruspentasulfide (P2S5) in refluxing toluene. The method avoids the use of expensive and hazardous transition metals and harsh reducing agents, as required by reported methods, and provides an attractive alternative to the existing methods for the conversion of organic
