In the presence of an alkene, three different modes of photocycloaddition with benzene derivatives can occur; the [2 + 2] or ortho, the [3 + 2] or meta, and the [4 + 2] or para photocycloaddition. This short review aims to demonstrate the synthetic power of these photocycloadditions.
在烯烃存在的情况下,苯衍生物可以发生三种不同模式的光环加成反应;[2 + 2]或邻位、[3 + 2]或间位和[4 + 2]或对位光环加成。本篇简短的综述旨在展示这些光环加成反应的合成威力。
