Provided is a catalyst to be used in a method for producing an aromatic compound at a high yield. A palladium complex represented by formula (D): (in the formula, X represents a chlorine atom or the like, A represents a C1-3 alkyl group, B represents a C4-20 alkyl group or a C5-10 cycloalkyl group, R 4 and R 5 represent a hydrogen atom, C1-20 alkoxy group, or the like, and R 6 , R 7 , and R 8 represent a hydrogen atom, C1-20 alkyl group, C6-20 aryl group, C4-20 heteroaryl group, or the like) or formula (D'): (in the formula, X, A, B, and R 4 -R 8 are defined in the same way as above). |
