Catalyst Reusability

A simple and environmentally benign room temperature synthesis of 1,2,4-triazolidine-3- thiones is described using Envirocat EPZ-10R as a solid acid catalyst in the aqueous medium. The use of Envirocat EPZ-10R as a green catalyst, reusability of the catalyst, water as a universal solvent and good yields of the product are the attractive features of the present method.
