Reaction of Arenediazonium Salts with Nitriles in the Presence of Sodium Carboxylates. A Convenient Synthesis of Unsymmetrical<i>N</i>-Aryl Acyclic Imides
Reactions of arenediazonium tetrafluoroborates (ArN2BF4), acetonitrile and sodium carboxylates (RCOONa) gave N-acyl acetanilides (ArN(COR)COCH3) in moderate to good yields (Ar=Ph, 2-MeC6H4, 3-MeC6H4, 4-MeC6H4, 2,6-(Me)2C6H3; R=Et, i-Pr, t-Bu, Ph). Acrylonitrile and benzonitrile could be used in the reaction instead of acetonitrile.
