availability of both phenols and amines, aniline synthesis through direct coupling between these starting materials would be extremely attractive. Herein, we describe a rhodium-catalyzed amination of phenols, which provides concise access to diverse anilines, with water as the sole byproduct. The arenophilic rhodium catalyst facilitates the inherently difficult keto–enol tautomerization of phenols by means of
鉴于酚类和胺类的广泛流行和易于获得,通过这些起始材料之间的直接偶联合成苯胺将极具吸引力。在这里,我们描述了一种铑催化的酚胺化,它提供了对各种苯胺的简洁访问,而水是唯一的副产物。亲惰性铑催化剂通过π-配位促进苯酚固有的困难的酮-烯醇互变异构化,允许随后与胺类脱水缩合。我们通过对具有各种电子特性的大量酚类和多种伯胺和仲胺进行反应,证明了这种氧化还原中性催化的普遍性。结构复杂的生物活性分子的后期功能化的几个例子,包括药物,
