Abstract

A process for preparing substituted biphenylsin which in the presence of a base and of a palladium catalyst selected from the group of: a) palladium-triarylphosphine or -trialkylphosphine complex with palladium in the zero oxidation state, b) salt of palladium in the presence of triarylphospine or trialkylphosphine as a complex ligand or c) metallic palladium applied to support if appropriate,in the presence of triarylphosphine or trialkylphosphine, in a solvent, with a diphenylborinic acid (III)
