Photocycloadditions of electron poor olefins to 2-aryl-1-pyrrolinium salts

Photocycloadditions of the electron poor olefins, acrylonitrile and methyl acrylate to a series of $\text{para}$-substituted 2-phenyl-1-pyrrolinium perchlorates have been explored as part of studies designed to test new synthetic methods.
