The dimerization of phenyl vinyl ether at an illuminated semiconductor surface has been demonstrated, and that reaction induced on ZnO was studied in detail. The involvement of surface-related processes has been shown to affect both the rate and stereochemistry of the system. Langmuir-Hinshelwood treatment has been found to be applicable for kinetic analysis. The effect of various quenchers has been described in terms of competitive adsorption with or without interference with electron-transfer processes on the surface. A reaction scheme involving the simultaneous formation of dimer both in the adsorbed state and in solution has been suggested, the former being the more important.
