Cobalt-catalyzed borylative reduction of azobenzenes using pinacolborane is developed. The simple cobalt chloride catalyst and reaction conditions make this protocol attractive for hydrazobenzene synthesis. This borylative reduction shows good functional group compatibility and can be readily scaled up to the gram scale. Preliminary mechanistic studies clarified the proton source of the hydrazine products
开发了使用频那醇硼烷的钴催化硼基化还原偶氮苯。简单的氯化钴催化剂和反应条件使该方案对于肼苯合成具有吸引力。这种硼化还原显示出良好的官能团相容性,并且可以很容易地放大到克级。初步机理研究阐明了肼产物的质子来源。这种钴催化的偶氮苯硼化反应提供了制备合成有用的二硼化肼的实用方案。
