ZnO-nanorods as economical catalyst for synthesis of 4-amino-2-iminodithiole derivatives using tetramethyl thiourea in water

Abstract

4-amino-2-iminodithiole derivatives were synthesised via multi-component reactions of tetramethyl thiourea, isothiocyanates and alkyl bromides in the presence of ZnO nanorods (ZnO-NR) as the catalyst in water at ambient temperature. These reactions provide low yields without catalysts. The catalyst exhibited significant reusable activity.
