The heterocyclic 2,3-diones 1 – 3 have been found to undergo photochemical and thermal 2+2-cycloaddition reactions via their 3-carbonyl group to diphenylketene and the diphenylketen-N-(4-methylphenyl)-imine. These reactions afford rearranged cycloadducts as well as 2+2-cycloreversion products.
杂环-2,3-二酮1 - 3已发现经历光化学和热2 +经由他们的3-羰基-2-环加成反应二苯基乙烯酮以与diphenylketen-N-(4-甲基苯基) -亚胺。这些反应提供了重排的环加合物以及2 + 2-环还原产物。
