The first example of the transition-metal-catalyzed direct intermolecular C–H bond addition to ketones was achieved by using a rhodium catalyst. A significant influence of the directing group on the reactivity was observed, and sterically more hindered directing groups could promote the reaction. In addition, intermolecular hydrogen bonding played a role in stabilizing the product. The substrate scope

铑催化剂实现了过渡
金属催化的直接分子间 C-H 键加成到酮的第一个例子。观察到导向基团对反应性的显着影响,空间位阻更大的导向基团可以促进反应。此外,分子间氢键在稳定产物方面发挥了作用。
喹啉衍
生物的底物范围非常好。
