current article reports in detail the preparation of two phosphonoterephthalic acids: 2-phosphonoterephthalic acid (1) and 2,5-diphosphonoterephthalic acid (2). Efficient, scalable syntheses have been developed for both compounds based on Pd-catalyzed coupling reactions of iodinated terephthalate esters. Phosphonoterephthalic acids are potentially useful as flame-retardant additives or as monomers for the
摘要 本文详细报道了两种磷酸对苯二甲酸的制备:2-磷酸对苯二甲酸(1)和2,5-二磷酸对苯二甲酸(2)。基于碘化对苯二甲酸酯的 Pd 催化偶联反应,已经为这两种化合物开发了有效、可扩展的合成方法。膦酸对苯二甲酸潜在地用作阻燃添加剂或用作构建酸-侧链聚合物链的单体。补充材料可用于本文。转至出版商的 Synthetic Communications® 在线版以查看免费的补充文件。图形概要
