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.
Keywords: alkyl bromide – ZnO nanorod (ZnO-NR) – tetramethyl thiourea – multicomponent reaction – isothiocyanate
