Selective and highly efficient synthesis of xanthenedione or tetraketone derivatives catalyzed by ZnO nanorods decorated graphene oxide

Abstract

ZnO nanorods decorated graphene oxide (GO/ZnO), having Bronsted and Lewis acid centers, was introduced as a selective, highly efficient and recoverable nanocatalyst for the pesudo three-component synthesis of diverse tetraketone or xanthenedione derivatives via condensation of aromatic aldehydes with 1,3-dicarbonyl compounds in short reaction times and good to excellent yields in H2O under refluxing and solvent-free conditions, respectively. Moreover, the GO/ZnO nanocomposite was recovered and reused at least four times without significant decrease in its activity. Low loading of the catalyst, high to excellent yields, eliminating of any toxic heavy metals or corrosive reagents for modification of the catalyst, simple separation and purification of the products, and reusability of the catalyst are the most significant advantages of this green protocol.
