In recent years, visible-light-induced organic transformations have taken a central role driving forward the progress of modern organic synthesis. These processes typically involve the transient generation of highly reactive radical intermediates, facilitating a diverse array of chemical reactions. Despite the abundance of synthetic strategies enabling the access of aryl and alkyl-centered radicals, the exploitation of photochemistry to generate highly reactive alkenyl radicals has remained notably underdeveloped. In this review, we present recent advancements in visible-light-induced transformations that proceed through the generation of alkenyl radicals from alkenyl-containing precursors, predominantly alkenyl halides, showcasing their application in various organic transformations.

通过烯基自由基中间体在可见光诱导反应方面取得进展

近年来，可见光诱导的有机转化在推动现代有机合成的进步中发挥着核心作用。这些过程通常涉及高反应性自由基中间体的瞬时生成，促进多种化学反应。尽管有大量的合成策略能够获得以芳基和烷基为中心的自由基，但利用光化学产生高反应性烯基自由基的开发仍然明显不足。在这篇综述中，我们介绍了可见光诱导转化的最新进展，这些转化是通过从含烯基前体（主要是烯基卤化物）生成烯基自由基来进行的，展示了它们在各种有机转化中的应用。
