Access to Aryl Mellitic Acid Esters through a Surprising Oxidative Esterification Reaction

摘要

A serendipitously discovered oxidative esterification reaction of cyclohexane hexacarboxylic acid with phosphorus pentachloride and phenols provides one-pot access to previously unknown aryl mellitic acid esters. The reaction features a solvent-free digestion and chromatography- free purifications and demonstrates the possibility of cyclohexaneto- benzene conversions under relatively mild, metal-free conditions.
