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 sequential assembly 1,2,3-triazole, 1,2,4-triazole, and tetrazole fragments into new stable polyazole. Along strategy, some known procedures been optimized to achieve better conversion, selectivity, and, general, overall efficiency.
