Herein, we describe the preparation and thorough characterization of a novel magnetically recoverable copper(i)-exchanged β-zeolite and its use as an efficient catalyst for the synthesis of 1,2,3-triazoles via the one-pot three-component reaction of organic halides, terminal acetylenes, and sodium azide in water. The magnetically recoverable β-zeolite could be easily separated from the reaction mixture with the aid of a magnet and reused in several consecutive reactions. Importantly, a series of characterizations studies allowed us to disclose the mechanism for the deactivation of the catalyst, and therefore to propose a method for its reactivation.

A simple procedure to obtain 4-acyl-1-substituted-1,2,3-triazoles, using a deep eutectic solvent (DES), ChCl and ethylene glycol at a 1:2 ratio, as the reaction medium is described. The products were obtained in high selectivity and good yields (70-84%).
