Abstract
TiO 2 -sensitized photo-oxidation of vanillin oxime and salicylaldehyde oxime has been studied. The increase in the polarity of the solvent increases yield of the photoproduct while increasing amounts of substrate and photocatalyst increase the yield of photoproduct only up to a certain limit. The rate of the reaction increases with the increase in the band gap of the semiconductor. A probable reasoning has been proposed giving structure-reactivity relationship of vanillin oxime and salicylaldehyde oxime with the isolated photoproduct. A reaction mechanism has been suggested.
