In this study, 2,4,4,6-tetrabromo-2,5-cyclohexadienone (TABCO) was prepared and used successfully as a stable phosphine-free reagent for the conversion of alcohols into alkyl thiocyanates and epoxides into 2-hydroxythiocyanates. The reactions seem to proceed via in situ generation of electrophilic sulfur species by reaction of NH4SCN and TABCO. This combined reagent worked well with both alcohols and epoxides in acetonitrile solvent and under solvent-free conditions.
