Abstract
Methanolysis of diphenic anhydrides (Va-c) obtained from diphenic acids (VIa-c) gave monomethyl diphenates (VIIa-c and VIIIa-c). The structures of these diphenates were confirmed by direct comparison of these compounds with authentic samples of VIIa-c and VIIIa-c prepared by oxidation of methyl 2'-formyl-2-biphenylcarboxylate derivatives (IXa-c and Xa-c) with potassium permanganate. The two directions of methanolysis of V to form VII and VIII are discussed.
