Abstract : Despite the ease of formation of silver ion complexes of olefins, photolysis of a variety of these complexes in several solvents afforded no apparent photoreaction but the cuprous chloride-1,5-cyclooctadiene complex structure of which has been determined has been shown to undergo photoreaction in ether solution at 2537A to produce tricyclo (188.8.131.52) octane. In the decarboxylation of cyclohexane carboxylic acid, the same products were obtained in the thermal reaction and in all of the photolytic ones. The esters and alkylbenzenes show the most pronounced differences in the two methods of decarboxylation; the combined yields of these components in the thermal reaction are over twice those obtained by any photolytic method. The decarboxylation of 2,2-dimethylbutyric acid, a tertiary acid, showed a more obvious difference. In the thermal reaction no 2-methylbutane was produced; in the photolytic reactions, however, this product was found. In the photolysis of primary carboxylic acids, shorter wavelength irradiation, 2537A, produces greater amounts of alkene and dimer than does the 3500A reaction. (Author)
