arylphosphonates at 20 °C within 1–2 h is reported using inexpensive SA as the catalytic promoter of the reaction. Mechanistic investigations suggest that the reaction proceeds via radical–radical coupling, consistent with the so-called persistent radical effect. The reaction tolerated a wide range of functional groups and heteroaromatic moieties. The synthetic usefulness and the unique reactivity of the
据报道,使用廉价的SA作为反应的催化促进剂,可在20°C下1-2小时内合成一种简单且可扩展的方法,以合成二苯基芳基膦酸酯。机理研究表明,该反应通过自由基与自由基的耦合进行,这与所谓的持久自由基效应相一致。该反应耐受各种官能团和杂芳族部分。在不同的一步转化中证明了所得膦酸酯的合成有用性和独特的反应性。
