The first ZnO-NP catalyzed Ugi type three-component (AB2C) reaction has been developed for the synthesis of 2-arylamino-2-phenylacetimidamide from an aldehyde, amine and isocyanide in aqueousmedia. This nanoparticle catalysed reaction (NPCR) is high yielding and has good atom economy as well as atom efficiency. The synthesized phenylacetimidamide yielded 2-amino-2-phenylacetamide on hydrolysis with
