use of Pd2dba3 with bulky, electron-rich ligands 1 or 2 and LiN(TMS)2 as the base for the coupling of amines with aryl halides containing hydroxyl, amide, or enolizable keto groups is described. This protocol expands the utility of palladium-catalyzed C-N bond formation by allowing for the use of aryl halides containing these functional groups, obviating the need for protecting group manipulations
[反应:见正文]描述了将Pd2dba3与庞大的富电子配体1或2和LiN(TMS)2用作胺与含有羟基,酰胺或可烯丙基酮基的芳基卤化物偶合的基础。通过允许使用含有这些官能团的芳基卤化物,该方案扩展了钯催化的CN键形成的应用,从而避免了对保护基团的操作。
