p‐Hydroxybenzoates were prepared directly from phenols through oxidative carbonylation at activated phenol C–H bonds in a procedure that is free of any requirements for co‐catalyst, co‐solvent or external ligand and uses molecular oxygen as a terminal oxidant for C–H bond oxidation.
对羟基苯甲酸酯是直接从苯酚中通过活化的酚C–H键上的羰基氧化反应制得的,该工艺无需任何助催化剂,助溶剂或外部配体的要求,而使用分子氧作为CH的末端氧化剂键氧化。
