Synthesis of 1‐(3‐(1‐substituted‐1,2,3‐triazol‐4‐yl)‐1,2,4‐triazol‐5‐yl)‐tetrazoles by Sequential Assembly of Azole Fragments.

Only few efficient methods for the preparation of polyazoles containing three or four nitrogen atoms in each azole cycle exist. We have developed a novel synthetic strategy that allows the sequential assembly of 1,2,3‐triazole, 1,2,4‐triazole, and tetrazole fragments into a new stable polyazole. Along the novel strategy, some known procedures have been optimized to achieve better conversion, selectivity, and, in general, overall efficiency. [ABSTRACT FROM AUTHOR]
