The reactivity of 2-(tetrazol-5-yl)-2H-azirines towards imines in the presence of Lewis acids was explored, which opened a way to new tetrazol-5-yl-1H-imidazole derivatives. The Zn(OTf)2-catalyzed reaction allowed the selectivesynthesis of 4-(tetrazol-5-yl)-1H-imidazole derivatives. The presence of
