The application discloses industry scalable methods of using bifunctional bidentate pyridone-carboxylic acid ligands, such as 2-methyl-2-(6-oxo-1,6-dihydropyridin-2-yl)propanoic acid, that enable room-temperature Pd-catalyzed C-H hydroxylation of a broad range of benzoic and phenylacetic acids with an industry-compatible oxidant, aqueous hydrogen peroxide, at room temperature. Further disclosed are methods of derivatization of the resulting hydroxylation products, synthesis of polyfluorinated natural products coumestan or pterocarpene from phenol building blocks, and hydroxylation of ibuprofen using this methodology,
该申请公开了使用双功能双齿吡啶酮-羧酸配体(如 2-甲基-2-(6-氧代-1,6-二氢吡啶-2-基)丙酸)的工业可扩展方法,这些配体能够在室温下用工业兼容氧化剂过氧化氢水溶液催化多种苯甲酸和苯乙酸的 C-H 羟基化反应。进一步公开了衍生羟化产物的方法、从苯酚结构单元合成多氟天然产物香豆素或紫檀烯的方法,以及使用该方法羟化布洛芬的方法、
