Zn@CS: An Efficient Cu-Free Catalyst System for Direct Azide-Alkyne Cycloadditions and Multicomponent Synthesis of 4-Aryl-NH-1,2,3-triazoles in H2O and DES

A highly efficient recoverable and reusable heterogeneous Zn-catalyst, chitosan supported ZnSO 4 . 7H 2 O (designated as Zn@CS) is synthesized via a simple synthetic route. Low catalyst loading, need of aqueous reaction media and sharp reduction of time requirement in comparison to the previously re...
