While the use of visible light in conjunction with transition metal catalysis offers powerful opportunities to switch between on/-off states of catalytic activity, the next frontier would be the ability to switch the actual function of the catalyst and resulting products. Here we report such an example of multi-dimensional catalysis. Featuring an easily prepared, bench-stable cobalt(I) hydride complex in conjunction with pinacolborane, we can switch the reaction outcome between two widely employed transformations, olefin migration and hydroboration, with visible light as the trigger.
虽然将可见光与过渡金属催化结合使用为在催化活性的开启/关闭状态之间切换提供了强大的机会，但下一个前沿领域将是能够切换催化剂的实际功能和所得产物。在此，我们报告这样一个多维催化的例子。以一种易于制备、在实验室中稳定的氢化钴（I）配合物与频哪醇硼烷相结合，我们可以以可见光为触发因素，在两种广泛使用的转化反应——烯烃迁移和硼氢化反应之间切换反应结果。
