Abstract

We have synthesized several 3-arylallyl acetates 1, 2, 3, 5 and 6, and E-3-(1-naphthyl)-2-propene-1-ol 4 for studying ionic photodissociation. Compounds 1, 2 and 3 underwent an efficient ionic photodissociation in polar solvents like acetonitrile and methanol leading to the formation of rearranged acetate and methyl ether products, as well as undergoing an EZ isomerization. The arylallyl alcohol 4 and the two arylallyl acetates 5 and 6 did not undergo ionic photodissociation. Quantum yields of product formation, quantum yields of fluorescence, solvent polarity effects and triplet-sensitization studies indicated that a highly polarized excited singlet state is responsible for the ionic photodissociation. Both the singlet- and triplet-excited states are effective in displaying EZ isomerization in 1, 2, 3 and 4. Compounds 5 and 6 are highly fluorescent, and the fluorescence may be the excited state deactivation pathway along with internal conversion.
