Background: Recently, ZnTiO3 nanopowder has become an important class of highly stable,
environmentally benign, reusable and heterogeneous catalyst.
Method: It has been prepared by means of a sustainable sol-gel method and thoroughly characterized
by XRD, SEM and HRTEM analysis.
Result: The dual nature of catalyst displays an imperative role towards quick transformation of amines,
formaldehyde and 1- or 2-naphthol to respective [1,3]-oxazine derivatives with good yields
(70-92 %) in eco-friendly water medium at room temperature (25-30 ºC) under stirring condition.
Keywords: ZnTiO3 nanopowder, reusable heterogeneous catalyst, aqueous medium, room temperature, 1, 3-oxazines, ecofriendliness.
