What is Additive-Free Synthesis of 3H-1,2,4-Triazol-3-ones via a Formal [3+2] Cycloaddition Reaction of Hydrazonoyl Chlorides with KOCN about?

## Abstract A direct and speedy approach for the synthesis of 1,5-disubstitued-3H-1,2,4-triazol-3-ones via a formal [3+2] cycloaddition reaction of hydrazonoyl chlorides with KOCN is described. The reaction proceeds in EtOH at room temperature with no need for any base and catalyst. KCl is the sole byproduct of this efficient synthetic procedure which can be isolated after reaction completion using water in which the products precipitated.
