Method for producing aromatic compound polymer

Abstract

A method for producing an aromatic compound polymer comprising oxidatively polymerizing one or more of aromatic compound(s) having two or more hydrogen atoms directly connected to aromatic ring(s), in the presence of an oxidizing agent, wherein the method employs a catalyst composed of a transition metal complex or a catalyst prepared from a transition metal complex and an activating agent, and said catalyst has a parameter P defined by the following formula (A) of 0.50 or more, and a parameter Eo defined by the following formula (B) of 0.50 [V] or more: P=Af/Ai   (A) and Eo =( Epa+Epc )/2 [V]  (B)

1 . A catalyst composed of a transition metal complex or prepared from a transition metal complex and activating agent, and having a parameter P of 0.50 or more, the parameter P defined by the above formula (A). 
     
     
         2 . A catalyst composed of a transition metal complex or prepared from a transition metal complex and activating agent, and having a parameter P defined by the above formula (A) of 0.50 or more, and a parameter Eo defined by the above formula (B) of 0.50 [V] or more. 
     
     
         3 . A vanadium di-nuclear complex represented by the following general formula (1-3): 
       
         
           
           
               
               
           
         
       
       (wherein A 1 , A 2 , A 3  and A 4  each independently represent an oxygen atom, or NR 11 , and B 1 , B 2 , B 3  and B 4  each independently represent —O— or —NR 12 —;
 R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7  and R 8  each independently represent optionally substituted hydrocarbon group or optionally substituted hydrocarbonoxy group; R 9  and R 10  each independently represent optionally substituted alkylene group, optionally substituted arylene group, —O—, —S—, —SO 2 — or —NR 13 —, and when R 9  and R 10  exist in a plural number respectively, they may be same or different each other; m and n each independently represent an integer of 1 to 7; R 11 , R 12  and R 13  each independently represent a hydrogen atom or optionally substituted hydrocarbon group; when R 11 , R 12  and R 13  exist in a plural number respectively, they may be same or different each other; when both of A 1  and A 2  and/or both of A 3  and A 4  are together NR 11  respectively, two R 11 s may combine to form divalent hydrocarbon group and connect A 1  and A 2  and/or A 3  and A 4  each other; and when both of B 1  and B 2  and/or both of B 3  and B 4  are together —NR 12 — respectively, two R 12 s may combine to form divalent hydrocarbon group and connect B 1  and B 2  and/or B 3  and B 4  each other).
