The second solvent is tetrahydrofuran, diethyl ether, dichloromethane, chloroform, and/or ethyl acetate. The mol weight of 2-isopropoxy-4,4,5,5-tetramethyl-1,3,4-tetrahydrofuran is 2-4 folds of 2,7-bromo-9,9-alkyl fluorine. The dosage of the catalytic agent is 0.0-10% 2,7-bi(4,4,5,5-tetramethyl-1,3,2-tetrahydrofuran)yl-9,9-alkyl fluorine. The catalytic agent is organic palladium or mixture of organic palladium and organophosphorus ligands. The organic palladium is Pd(PPh3)4, Pd(OAc)2,Pd2(dba)3 or Pd(PPh3)2Cl2. The organophosphorus ligands are trihexylphosphine or P(o-Tol)3. The mol ratio of the organic palladium and organophosphorus ligands is 1:1-20 in the mixture of 3eorganic palladium and organophosphorus ligands. The alkali liquor is sodium hydroxide aqueous solution, sodium carbonate aqueous solution, sodium bicarbonate aqueous solution, or tetraethyl ammonium hydroxide aqueous solution. The dosage of the alkali liquor is 5-10 folds of 2,7-bi(4,4,5,5-tetramethyl-1,3,2-tetrahydrofuran)yl-9,9-alkyl fluorine. The first organic solvent is methylbenzene, glycol dimethyl ether, tetrahydrofuran, diethyl ether, dichloromethane, chloroform, and/or ethyl acetate. Preferred Definitions:    m=greater than 6 and less than or equal to 12;    R1, R2=1-18C alkyl; and    R3=1-12C alkyl or 6-20C aryl alkoxy.
