A Simple and Green Procedure for the Synthesis of 5‐Arylidenerhodanines Catalyzed by Diammonium Hydrogen Phosphate in Water

Abstract

A simple and efficient procedure for the synthesis of 5-arylidenerhodanines by condensation of aromatic aldehydes with rhodanine in water using diammonium hydrogen phosphate as catalyst is described. The procedure offers several advantages including environmentally friendly, mild reaction conditions, short reaction times, high yields, and simple experimental and work-up procedures.
