Synthesis of isothiocyanates
An electrochemical benzylic isothiocyanation provides isothiocyanate derivatives in a highly chemo- and site-selective manner under external oxidant-free conditions. The method exhibits high functional group compatibility and is suitable for late-stage functionalization of bioactive molecules.

A novel and highly selective method uses triphenylphosphine, diethylazodicarboxylate and NH4SCN for the conversion of alcohols, thiols, carboxylic acids, silyl ethers, and silyl carboxylates to their corresponding thiocyanates.
