rearrangement of barrelenes, oxa-di-π-methane rearrangement of β,γ-unsaturated ketones and photodimerization of acenaphthylene as probe reactions. The two methods, heavy cation effect and triplet sensitization, are well established solution techniques and these work well within zeolites. The Zimmerman rearrangement of dibenzobarrelene is enhanced even within Li+ and Na+ exchanged zeolites and these are
已经通过利用桶烯的齐默曼重排,β,γ-不饱和酮的氧-二-π-甲烷重排和的光二聚化作为探针反应,建立了在沸石内产生三分子有机分子的方法。重阳离子效应和三重态敏化这两种方法是公认的解决方法,它们在沸石中效果很好。即使在Li +和Na +交换的沸石中,二苯并戊烯的齐默曼重排也得到增强,这被认为是减慢了从S 1向二苯并环辛酸酯的重排的结果。通过阳离子-π相互作用。本文描述的方法提供了探索沸石环境对三重态反应提供控制的机会。
