Efficient Synthesis of 5-Substituted 1H-Tetrazoles Catalysed by Silver(I) Bis(trifluoromethanesulfoyl)Nimide

An efficient method is developed for the synthesis of 5-substituted 1H-tetrazoles through the [3 + 2] cycloaddition reaction of nitriles with sodium azide using silver(I) bis(trifluoromethanesulfonyl)imide (AgNTf2) as a catalyst. This procedure provides mild reaction conditions, short reaction times and high yields.
