Design and Preparation of Platinum Anchored on Cellulose as Heterogeneous Nanocatalyst for Synthesis of Bis-Coumarin Derivatives

Abstract

In this research, an effective, stable and separable platinum nanocatalyst was fabricated and identified. This nanocatalyst presented well to excellent activities and reusabilities in the synthesis of bis-coumarins processes through the reaction of aromatic aldehydes with 4-hydroxycoumarin. Fast, clean, highly purity and yield of products, short reaction times and highly efficient conditions are some advantages of this protocol. The nanocatalyst was characterized by XRD, SEM, EDX, TEM and FTIR techniques. In this research, a highly stable and separable platinum nanocatalyst was fabricated and identified. The nanocatalyst presented well to excellent activities and reusabilities in the synthesis of bis-coumarins processes including aromatic aldehydes with 4-hydroxycoumarin.
