Efficient heterogeneous silver nanoparticles catalyzed one-pot synthesis of 5-substituted 1H-tetrazoles

Silver nanoparticles (AgNPs), characterized by TEM, EDX and UV studies were used as an efficient heterogeneous catalyst for the synthesis of 5-substituted 1H-tetrazoles from various nitriles possessing different functional groups in excellent yields. All title compounds were characterized by spectroscopy (H-1 NMR, C-13 NMR and IR) and crystallography. (C) 2014 Published by Elsevier B.V.
