Meglumine Encapsulated CuI: A Green Heterogeneous Catalyst Derived from Low Value Biomass Meglumine to Access 1,2,3-Triazole Scaffolds

Abstract

In current state of the art, we report a solitary pot green tactic for the synthesis of task-specific CuI nanoparticles (NPs) encapsulated by eco-healthy low value biomass (LVBM) meglumine. The synthesized meglumine encapsulated CuI NPs (Meg-Cu) material was characterized by using various analytical tools, and it was found that CuI NPs (with <100 nm size) were encapsulated by meglumine molecules interacting with −NHMe and −OH functionalities of meglumine. Meg-Cu was utilized marvelously as a catalyst for the creation of 1,2,3-triazole scaffolds. The established protocol allowed the synthesis of 1,2,3-triazoles via both two- and three-component routes. Moreover, the protocol was efficiently used for the synthesis of 1,2,3-triazoles initiated from anilines via in-situ generation of aromatic azides. The catalyst was successfully recycled up to three times without a loss of catalytic activity. The structural integrity of the spent catalyst was investigated by FT-IR and TGA analysis. The present protocol embraces features like a short reaction time, wide substrate scope, environment-friendly reaction conditions, and good to excellent yields.
