Patent ID: 6878663

Claim:
A method for producing a palladium-complex compound represented by formula (2), Ar 1 -PdL 2 X (2) where Ar 1 is an aryl group represented by formula (6); where R 2 is a trifluoromethyl group, and m is an integer 4 from 2 to 4, each L is independently a phosphine ligand, and two of L are optionally bonded together to form a diphosphine, and X is a halogen that is fluorine, chlorine, bromine or iodine, trifluoromethanesulfonate group, an alkylsulfonate group having a carbon atom number of 1-4, or a substituted or unsubstituted arylsulfonate group, said method comprising: reacting an aromatic compound represented by formula (1), Ar 1 X (1) where Ar 1 and X are defined as above, with a palladium compound and a phosphine derivative, in the presence of a basic substance, thereby obtaining said palladium-complex compound, Ar 1 -PdL 2 X.
