摘要

Abstract The photochemistry of the diphenyl β, γ-enones 2 and 3 and the methyl-and phenyl- substituted α-phenyl ketones 4-9 has been studied, using mainly benzene as solvent. Irradiation of 2 with λ 300 nm leads to the 1, 3-acyl shift (1, 3-AS) product 17, relatively small amounts of the decarbonylation products 15 and 16, and the photo-oxidation products benzophenone (18) and the α, β-unsaturated aldehyde 19. Direct irradiation of the 1, 3-AS ...
