Anchoring Cu nanoparticles on functionalized multi‐walled carbon nanotube for regioselective synthesis of 1,2,3‐triazoles via click reaction

Unique properties of 1,2,3‐triazoles on the one hand and necessity of usage of an efficient catalyst with fidelity in principles of green chemistry on the other hand impelled us to design and synthesis of a novel heterogeneous nanocatalyst (Cu@Arg‐MWCNTs) with simple synthesis, immense power, high regioselectivity, and easy separation and recyclability. The Cu@Arg‐MWCNT structure is characterized by different analyses and used for the synthesis of various triazoles. Its high catalytic activity is confirmed by high yields and short reaction times under mild conditions in click reaction. Unique properties of triazoles, encouraged us for design and synthesis of Cu@Arg‐MWCNT as a new heterogeneous nanocatalyst. High catalytic activity in water medium for regioselective synthesis of triazoles via click reaction and its reusability and fidelity in principles of green chemistry are among its interesting features that bring Cu@Arg‐MWCNT up as a unique and worthwhile catalyst. ​
