Synthesis of isothiocyanates

Recent Literature


A facile and general protocol for the preparation of isothiocyanates from alkyl and aryl amines relies on a tosyl chloride mediated decomposition of a dithiocarbamate salts that are generated in situ by treatment of amines with carbon disulfide and triethylamine. Vairous alkyl- and arylisothiocyanates have been prepared in good yield.
