    A nickel-promoted cascade annulation reaction for the facile synthesis of 3H-1,2,4-triazol-3-ones from readily available hydrazonoyl chlorides and sodium cyanate has been developed. The transformation occurs through a cascade nickel-promoted intermolecular nucleophilic addition–elimination process, intramolecular nucleophilic addition, and a hydrogen-transfer sequence. The method has been successfully

    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.

    摘要:本文介绍了一种直接快速合成1,5-二取代-3H-1,2,4-三唑-3-酮的方法,通过与KOCN的[3+2]环加成反应。该反应在室温下在EtOH中进行,无需任何碱和催化剂。 KCl是这种高效合成方法的唯一副产物,可以使用分离后反应完成后沉淀的产物。
