Patent ID: 7122711

Claim:
A method for producing a biaryl compound of formula (I): wherein R 1 is the same or different and independently denotes a substituted or unsubstituted aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, or a, fluorine atom, A denotes an aromatic hydrocarbon ring having from 6 to 14 carbon atoms or a pyridine ring, B denotes an aromatic hydrocarbon ring having from 6 to 14 carbon atoms, k and m independently denote an integer of from 0 to 5, and l denotes an integer of 1 or 2, which method comprises reacting an aromatic compound of formula (II): wherein R 1 , k and l denote the same as defined above, and X 1 denotes a leaving group, with a Grignard reagent of formula (III): wherein R 2 , B, and m denote the same as defined above, and X 2 denote a chlorine, bromine or iodine atom, in the presence of a cyclic ether, or an acyclic ether having two or more ether oxygens in the molecule and a nickel catalyst consisting essentially of a nickel compound and a nitrogen-containing compound, provided that the nitrogen-containing compound is not 2,2′-bipyridyl.
