Sreedhar, B. published the artcileCuFe2O4 nanoparticles: a magnetically recoverable and reusable catalyst for the synthesis of 5-substituted 1H-tetrazoles, Recommanded Product: 5-(4-(Trifluoromethyl)phenyl)-1H-tetrazole, the publication is Tetrahedron Letters (2011), 52(28), 3565-3569, database is CAplus.
An efficient and economical protocol for the synthesis of 5-substituted 1H-tetrazoles from various nitriles and sodium azide is described using magnetically recoverable and reusable CuFe2O4 nanoparticles. A wide variety of aryl nitriles underwent [2+3] cycloaddition under mild reaction conditions to afford tetrazoles in good to excellent yields. The catalyst was magnetically separated and reused five times without significant loss of catalytic activity.
