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.
已经研究了二苯基β,γ-烯酮2和3以及甲基和苯基取代的α-苯基酮4-9的光化学,主要使用苯作为溶剂。用λ300 nm辐照2会导致1,3-酰基转移(1,3-AS)产物17,相对少量的脱羰产物15和16以及光氧化产物二苯甲酮(18)和α ,β-不饱和醛19。1,3- AS产物直接照射17个收率15,16,18和19,但没有2。
