Abstract: It was found that the product yields of oxidative coupling of anisole producing 4,4'-dimethoxybiphenyl on homoionic forms of montmorillonite decrease in the same order as reduction potential of metallic ions, i.e. Fe³⁺, Cu²⁺, Co²⁺, Al³⁺ , and Ca²⁺. No expressive difference has been observed between bentonite and montmorillonite during their application. The course of oxidative coupling of a benzene derivative is significantly influenced by the substituents on the benzene ring.
