An iron-catalyzed oxidative coupling/cyclization reaction for the synthesis of benzoxazoles at room temperature is reported. This reaction was enabled by an inexpensive iron(III) catalyst by treating readily available phenol derivatives with benzoyl aldehyde oximes. Mechanistic studies show that benzoyl aldehyde oxime is not only used as a substrate, but also serves as an ancillary ligand to support
据报道在室温下铁催化的氧化偶联/环化反应用于合成苯并恶唑。该反应由廉价的铁(III)催化剂通过用苯甲酰基醛肟处理易得的苯酚衍生物来实现。机理研究表明,苯甲酰醛肟不仅用作底物,而且还用作辅助配体以支持铁盐促进转化。
