[reaction: see text] Palladium-catalyzed directed C-H activation/oxygenation reactions have been explored in a series of meta-substituted aryl pyridine and aryl amide derivatives. These transformations tolerate a diverse array of electron-donating and electron-withdrawing meta-substituents and generally proceed with high levels of regioselectivity for functionalization of the less sterically hindered
[反应:见正文]已经在一系列间位取代的芳基吡啶和芳基酰胺衍生物中探索了钯催化的CH活化/氧化反应。这些转化可耐受各种各样的供电子和吸电子的间位取代基,并且通常以较高水平的区域选择性进行,以使空间位阻较小的邻-CH键官能化。
