Photochemical reactions of methoxybenzenes with acrylonitrile
Abstract
Irradiation of a mixture of anisole and acrylonitrile in acetonitrile and in methanol gave [2 + 2]cyclo-adducts and cyanoethylated products, respectively, while irradiation of dimethoxybenzenes in the presence of acrylonitrile in methanol and in acetonitrile gave the corresponding cyanoethylated products and only dimers of acrylonitrile.
