Pd‐Catalyzed Synthesis of Aryl Esters Involving Difluorocarbene Transfer Carbonylation

Abstract A Pd‐catalyzed three‐component intermolecular reaction between aryl halides, ClCF 2 COONa and phenols is developed. A series of aryl benzoates were synthesized in up to 84 % yield via difluorocarbene transfer carbonylation. It is devoted to acquiring the targeted products by construction of new C−C, C=O and C−O bonds in a one‐pot, one‐step process. The feature of this method includes the use of readily available starting materials, showing outstanding resistance to spatial obstruction and simple operation procedure with mild reaction conditions. Therefore, this makes the methodology a useful alternative to other schemes typically used for the synthesis of aryl esters.
