A electrochemical method for the synthesis of 3,5-disubstituted-1,2,4-thiadiazoles through NH 4 I-mediated dimerization of thioamides is reported. Using the inexpensive NH 4 I as electrolyte and catalyst, this electrosynthesis approach requires no oxidizing agents and enables the convenient production of diverse 1,2,4-thiadiazoles products. The approach is an example of SÀN bond construction through the electrochemical method.

This study reports the environment‐friendly electrochemical transformation of structurally diverse phosphorus compounds and alcohol into phosphonates in the presence of ammonium iodide as electrolyte and redox catalyst in acetonitrile at ambient temperature. This method for P−O bond formation exhibits remarkable features, such as transition metal‐ and oxidant‐free conditions. A reliable mechanism is proposed after control and cyclic voltammetry experiments.magnified image
