“…Chemistry of nitrogen-rich heterocycles gains immense importance due to their diverse application . Specifically, tetrazoles are an ubiquitous structural motif very often utilized in pharmaceuticals (Figure ), as ligands in coordination chemistry, in organocatalysis, as synthons in organic synthesis as well as in various materials science applications including polymers, photosensitive agents, energy materials, and specialty explosives . In the literature, a plethora of methods were reported for the synthesis of 5-substituted 1 H -tetrazole derivatives. , Nevertheless, those protocols have some drawbacks such as, (i) high catalyst loading, (ii) expensive reagents, (iii) harsh reaction conditions; water sensitivity and the involvement of dangerous hydrazoic acid, and (iv) prolonged reaction time and elevated temperature. , Hence, development of an efficient, economical and eco-friendly one-pot methodology to construct the titled heterocyclic frame-works with wide substrate scope is a challenging scientific mission.…”
