Allyl nitriles were synthesized from the reactions of arylpropiolic acids with azobis(alkylcarbonitriles) (AIBN or ACCN). In the presence of Cu(OAc)2 as a catalyst and pyridine as the solvent, the (E)-stereoisomer was formed as the major product. This transformation shows good tolerance toward alkoxy, halogen, alcohol, amine, ester, and ketone functional groups. When the reaction was conducted with
