PROCESS FOR PRODUCTION OF DIMERS OF AROMATIC MONOHYDROXYL COMPOUNDS

摘要

A process for production of dimers of aromatic monohydroxyl compounds, characterized by conducting the oxidative coupling of an aromatic compound represented by the general formula [I]: Ar-OH [I] (wherein Ar is an optionally substituted aromatic group) in the presence of a copper salt in a nitrogenous polar solvent. According to this process, dimers of aromatic monohydroxyl compounds can be produced in high yield.
