Surface Photochemistry: CdS Photoinduced Cis-Trans Isomerization of Olefins

Article abstract of DOI:10.1021/j100272a048

The CdS powder photomediated cis-trans isomerization of six styrene derivatives has been demonstrated.The reaction with cis-stilbene is quenched by electron donors (methoxybenzenes and pyrene) and is affected by the amount of CdS used, light intensity, and the temperature.A minimal simple scheme involving the radical cation is proposed, as a basis for further work, to which Langmuir-Hinshelwood and Freundlich kinetic treatments are applied, the latter somewhat more successfully.The presence of oxygen inhibits the reaction.
