catalyst, employing a 6,6′‐dimethyl‐2,2′‐bipyridine ligand, promotes both the aerobic oxidative Heck coupling and dehydrogenation reactions of cyclohexenones. These reactions may be combined in a one‐pot sequence to enable the straightforward synthesis of meta‐substituted phenols (see scheme).
争夺(间)位:一种新型双阳离子钯(II)催化剂,采用 6,6'-二甲基-2,2'-联吡啶配体,促进环己烯酮的有氧氧化 Heck 偶联和脱氢反应。这些反应可以以一锅法顺序组合,以实现间位取代酚的直接合成(参见方案)。
