The first intrazeolite-photoinduced rearrangement of a five-membered heterocycle is reported. A completely different behavior compared to solution irradiations has been observed. The zeolite's role in directing the photoreaction of 3-phenyl-1,2,4-oxadiazoles toward the formation of the corresponding 1,3,4-oxadiazoles in a ring contraction−ring expansion route is discussed.
据报道,第一次沸石内光诱导的五元杂环重排。与溶液辐照相比,已经观察到完全不同的行为。讨论了沸石在环收缩-环膨胀途径中指导3-苯基-1,2,4-恶二唑的光反应朝相应的1,3,4-恶二唑的形成的作用。
