Cobalt-catalyzed C–H activation by means of oxazolinyl assistance set the stage for versatile direct amidations with ample substrate scope. Thus, a high-valent cobalt(III) catalyst enabled C–H amidations with excellent levels of positional and chemo-selectivities. Mechanistic studies provided strong support for a kinetically relevant C–H functionalization.
借助恶唑啉基助剂的钴催化的C–H活化为具有广泛底物范围的通用直接酰胺化奠定了基础。因此,高价钴(III)催化剂可以使C–H酰胺化具有极好的位置选择性和化学选择性。力学研究为动力学相关的C–H功能化提供了有力的支持。
