A practical method for the synthesis of various thiocyanated 5-membered aromatic heterocycles through electrochemical cross-coupling of heterocycles (pyrazoles, pyrroles, furans and thiophenes) with NH4SCN under chemical oxidant- and exogenous electrolyte-free conditions was developed. NH4SCN played dual roles of a supporting electrolyte and a thiocyanated reagent, and thus simplify the reaction sys...
