Free‐radical‐mediated copper‐catalyzed triazole formation under UV‐irradiation

Abstract

Methoxy‐polyethylene glycol (MPEG)‐doped Cu (I)‐polyaniline acts as an efficient catalyst for the 1,2,3‐triazole formation reaction. The catalyst shows excellent performance when the reaction was carried out under ultraviolet irradiation conditions due to the photo‐induced free‐radical formation from the MPEG. A detailed mechanistic discussion on the free‐radical generation, free‐radical‐mediated hydrogen abstraction and triazole formation has been outlined in this manuscript. The catalyst system is equally active for one‐pot multi‐component strategies for the title reaction.

Translation of a chemical reaction to electrical signal generation: an organic–inorganic complexation strategy

“…9 Copper ions play a crucial role in the physiological system, and the interaction study between copper and organic ligands, with biological relevance, is considered as one of the most fertile pitches in multidisciplinary research platform. Copper, a redoxactive element, in the form of zero-valent, uni-valent and bi-valent, not only serves the role of a catalyst [10][11][12][13] but also acts as a structural co-factor for a wide range of biomolecules. 14 Among numerous biomolecules, protein molecules have attracted tremendous attention for the integration of multifunctional molecular devices.…”
