Photochemistry has become a key area of research in synthetic chemistry over the last few decades. More recently, interest has grown in merging this area with transition metal catalysis to develop new reactivity. One key photoinduced step in this context is ligand dissociation from transition metal complexes. This has been used to develop light-gated catalysis, allowing for on/off control over a reaction. However, this concept can only result in a single product outcome. Our group has focused on the development of cobalt-catalyzed reactivity switches, enabled by a simple photodissociation step, which promotes one mechanistic path or another. As such, we can use a single catalytic platform to yield two different outcomes depending on whether the reaction is irradiated with light or not. This short review will focus on works in this area by our group and others.

在过去的几十年里，光化学已成为合成化学研究的一个关键领域。最近，人们越来越关注将该领域与过渡金属催化相结合以开发新的反应性。在这种情况下，一个关键的光诱导步骤是配体从过渡金属配合物解离。这已被用于开发光门催化，允许对反应进行开/关控制。然而，这个概念只能产生单一的产品结果。我们的团队专注于钴催化反应开关的开发，通过简单的光解步骤实现，从而促进一种或另一种机械路径。因此，我们可以使用单一催化平台来产生两种不同的结果，具体取决于反应是否受到光照射。这篇简短的评论将重点关注我们小组和其他人在该领域的工作。
