UV.-irradiation (λ ≥ 327 nm) of the α,β-unsaturated γ,δ-epoxy ketone 2 in pentane gives the isomers oxidoketone 3 and diketone 4, in high yield. On treatment with BF3O(C2H5)2, 2 undergoes rearrangement to the diketone 4 and the isomeric lactone 8 and yields also the dimer 9.
戊烷中α,β-不饱和γ,δ-环氧酮2的紫外线照射(λ≥327 nm)可以高收率得到异构体氧化酮3和二酮4。在用BF 3 O(C 2 H 5)2处理时,2重排成二酮4和异构内酯8,还产生二聚体9。
