Acyl hydrazides are widely found in bioactive compounds and have important applications as versatile synthetic intermediates. In the current report, a photoredox-catalyzed hydroacylation of azobenzenes was disclosed with carboxylic acids as the acylation reagent, affording a variety of N,N′-disubstituted hydrazides. The process possesses the advantages of mild reaction conditions, broad substrate scope
酰肼广泛存在于生物活性化合物中,作为多功能合成中间体具有重要的应用。在本报告中,公开了以羧酸为酰化试剂的偶氮苯的光氧化还原催化加氢酰化反应,得到多种N,N'-二取代酰肼。该工艺具有反应条件温和、底物范围广、效率高等优点。初步的机理研究表明,应该涉及到偶氮化合物中酰基的加成。
