An efficient and convenient iridium(III) catalyzed ortho-C–H bond amidation of weakly coordinating benzamides treated with readily available sulfonyl azides as the amino source has been described. In this transformation, ionic liquids represents an ideal reaction medium, giving rise to a broad range of amidation products under mild conditions in the open air. This protocol offers moderate to excellent
已经描述了用容易获得的磺酰叠氮化物作为氨基源处理的弱配位苯甲酰胺的有效且方便的铱( III )催化邻-C-H键酰胺化。在这种转变中,离子液体代表了一种理想的反应介质,在温和的露天条件下可产生多种酰胺化产物。该协议提供中等至优异的化学产量、独特的区域选择性和良好的官能团耐受性。
