We report an efficient method for the oxidativedehydrogenation of hydrazines and diarylamines in aqueous ethanol using Anderson-type polyoxomolybdate-based iron(III) as a catalyst and hydrogen peroxide as an oxidant. A series of azo compounds and tetraarylhydrazines were obtained in moderate to excellent yields. The reaction conditions and substrate scopes are complementary or superior to those of
我们报告了一种使用安德森型多氧钼酸铁 ( III ) 作为催化剂和过氧化氢作为氧化剂在乙醇水溶液中氧化脱氢肼和二芳基胺的有效方法。以中等至极好的收率获得了一系列偶氮化合物和四芳基肼。反应条件和底物范围补充或优于更成熟的方案。此外,该催化剂在水中表现出良好的稳定性和重复使用性。初步的机理研究表明,该反应涉及一个自由基过程。
