PROBLEM TO BE SOLVED: To provide an industrially-useful heterogeneous catalyst for coupling reaction, and a method for producing a triarylamine compound and/or triarylamine polymer using the heterogeneous catalyst.SOLUTION: The heterogeneous catalyst for coupling reaction includes a carrier, a palladium compound, and tri (tert-butyl) phosphine, and is characterized in that the palladium compound content in weight is 0.03 to 0.2 times the carrier weight in terms of palladium atom and the tri (tert-butyl) phosphine content in mole is 0.6 to 12 times one palladium atom mole in the palladium compound. In addition, the heterogeneous catalyst is used. |
