A practical synthetic method for 4-thiocyanato-1 H -pyrazoles through the electrochemical cascade reaction of hydrazines , 1,3-diones and NH 4 SCN under metal-, chemical oxidant- and external electrolyte-free conditions was established. Importantly, both a gram-scale synthesis of 4-thiocyanato-1 H -pyrazoles and five one-pot sequential transformations starting from hydrazine were successfully accomplished.
