Cu-metformin grafted on multi walled carbon nanotubes: Preparation and investigation of catalytic activity

Abstract

An efficient and one-pot procedure for the preparation of 1,4-disubstituted 1,2,3-triazoles derivatives from reactions of various aryl azides and different terminal alkynes in the presence of functionalized carbon nanotubes (CNTs) by metformin and subsequent coordination with copper(I) has been developed. The catalysts showed environmentally benign character, which can be easily prepared, stored, and recovered several times without obvious significant loss of activity.
