“…Goswami and colleagues have reported the synthesis of two readily producible, reusable, and morphology-controllable copper nanostructures attached to reduced graphene oxide (rGO), namely rGO-CuNRs and rGO-CuNPs. [92] Cu-nanorods (CuNRs) with an average diameter of ~20 nm and length of ~1 μ, and Cu-nanoparticles (CuNPs) with an average diameter of ~30 nm were decorated on reduced graphene oxide (rGO) nanosheets. The crystal lattice plane distance in CuNRs indicated possible Cu(I) and Cu(II) presence in Cu 2 O (111) and CuO (110) planes.…”

The Huisgen cycloaddition, often referred to as 1,3‐Dipolar cycloaddition, is a well‐established method for synthesizing 1,4‐disubstituted triazoles. Originally conducted under thermal conditions [3+2] cycloaddition reactions were limited by temperature, prolonged reaction time, and regioselectivity. The copper catalyzed azide‐alkyne cycloaddition (CuAAC) has emerged as a prominent method for producing 1,2,3‐triazole with excellent yields and exceptional regioselectivity. Copper catalysts conventionally facilitate azide‐alkyne cycloadditions, but challenges include instability and recycling issues. In recent years, there has been a growing demand for heterogeneous catalysts in various chemical reactions. The present review covers recent advancements from year 2018 to 2023 in the field of click reactions for obtaining 1,2,3‐triazoles through Cu catalyzed 1,3‐dipolar azide‐alkyne cycloaddition and the properties of the catalyst, reaction conditions such as solvent, temperature, reaction time, and the impact of different heterogeneous copper catalysts on product yield.
