Electric Literature of C6H5N5. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-(4-Pyridyl)-1H-tetrazole, is researched, Molecular C6H5N5, CAS is 14389-12-9, about Facile, highly efficient and novel method for synthesis of 5-substituted 1H-tetrazoles catalysed by. Author is Esirden, Ibrahim; Basar, Erhan; Kaya, Muharrem.
A series of 5-substituted 1H-tetrazole derivatives I [R = 4-pyridinyl, 4-O2NC6H4, 4-acetamidophenyl, etc.] was synthesized via copper(I) chloride catalyzed [3+2] cycloaddition of aryl nitriles with sodium azide. The salient features of this protocol were short reaction times, high yields, environmental friendly catalyst and simple procedure.
