<Reason why the effect of the present invention is exhibited>
Although the reason why the effects of the present invention are exerted is not necessarily clear, the following mechanism of action is assumed.
For example, in the conventional method for producing a polymer compound using a palladium complex, the ligands used are monodentate phosphine ligands, 1,1′-bis(diphenylphosphino)ferrocene and 1,2- Some bidentate phosphine ligands, such as bis(diphenylphosphino)ethane, especially leave unreacted aromatic monomers when these ligands are used.
The present inventors considered the cause of this to be ring-walking (a phenomenon in which a transition metal such as palladium moves on an aromatic ring while interacting with π electrons of the aromatic ring).
Specifically, when a palladium complex containing a conventional ligand is used, ring-walking is likely to occur because polymer chains are less likely to dissociate from palladium after reductive elimination in the palladium-catalyzed reaction. On the other hand, when the palladium complex of the present embodiment is used, the polymer chain is easily dissociated from palladium, so ring-walking is less likely to occur, and as a result, the sequential polymerizability is increased, and the remaining after the reaction It is believed that the amount of monomer is sufficiently reduced.
