Patent ID: 6914152

Claim:
A method for selectively producing an asymmetrically substituted biphenyl compound comprising oxidatively coupling an aromatic compound represented by formula (1): wherein R represents an alkyl group of 1 to 5 carbon atoms, an alkoxy group of 1 to 5 carbon atoms, an alkoxyl carbonyl group of 1 to 5 carbon atoms, an aryloxy carbonyl group, an alkanoyloxy group of 1 to 5 carbon atoms, an alkanoyloxyalkyl group of 1 to 5 carbon atoms, an alkyl group of 1 to 5 carbon atoms, the hydrogen atom of which is substituted with an acetyl group or a halogen atom, a nitro group, and a halogen atom; and in represents an integer of 1 to 3, in the presence of a palladium salt, a copper salt, and a bidentate ligand compound capable of forming a complex with the palladium salt via the nitrogen atom and the oxygen atom in the molecule thereof in an atmosphere containing molecular oxygen, and wherein the selectivity to the asymmetrically substituted biphenyl compound can be increased 60 to 99%.
