Abstract

A general and practical green chemistry route to the synthesis of 5-arylidenethiobarbituric acids is described from aromatic aldehydes and thiobarbituric acid under three different sets of reaction conditions: water without catalyst conditions, microwave irradiation, and grinding method using NH4OAc as a catalyst at room temperature.
