Cu-catalyzed domino decyanation and cyanation reaction of acyl cyanides with amines or alcohols have been developed. The cyanosources were generated in situ via C–CN cleavage yielding the corresponding cyano substituted amides or esters in moderate to excellent yields. This approach features a cheap copper catalyst, domino decyanation and cyanation reaction, readily available starting materials, broad
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.
