An efficient, basic resin mediated, one-pot synthesis of O-alkyl-S-methyl dithiocarbonates from the corresponding alcohols

Abstract

A novel process for the one-step conversion of primary and secondary alcohols into their O-alkyl-S-methyl dithiocarbonates was developed using Amberlite IRA 400 (basic resin) in presence of carbon disulfide. O-Alkyl-S-methyl dithiocarbonates of various alcohols were isolated in very good to excellent yields. This protocol is mild and efficient compared to other existing methods.
