Irradiation of 2-phenyl and 2-isobutenyl-1-pyrrolinium salts in solutions of alcohols and ethers containing α-hydrogens leads to productions of addition products.In addition, alcohols and ethers having low ionization potentials and α-hydrogens serve as efficient quenchers of fluorescence from 2-phenyl-1-pyrrolinium salts.Deuterium isotope effects on fluorescence quenching rate constants appear to implicate electron transfer mechanisms in photoaddition and quenching pathways.
