Abstract
The dimer of methyl 2-naphthoate (I) has been found to undergo efficie nt cycloreversion to its monomer, methyl naphthalene-2-carboxylate (2) on illuminated ZnO and TiO2 but not on CdS. An electron transfer and cation radical chain mechanism is proposed. Quantum yields, solvent ef fect. the role of oxygen, and the quenching of the reaction were inves tigated, and were consistent with the proposed mechanism.
