Synthesis of substituted 2,2'- and 4,4'-biphenyldiols using oxidative coupling reaction

Abstract

Based on the oxidative coupling reaction, methods for the synthesis of substituted 2,2'- and 4,4'-biphenyldiols have been developed. These biphenyldiols were not described in the literature. The article presents the potential applications and limitations of the method using potassium ferricyanide and iron (III) chloride hexahydrate.
