Three-component reaction between isonicotinohydrazide, potassium selenocyanate and aroyl chlorides: synthesis of 1,2,4-triazole-3-selones

摘要

A one-pot method for the synthesis of six novel 1,2,4-triazole-3-selones in excellent yields at room temperature has been achieved via reaction between potassium selenocyanate and an aroyl chloride followed by the addition of isonicotinohydrazide.
