The synthetic route is as follows., Application In Synthesis of 1,4-Diiodo-2,3,5,6-tetramethylbenzene
1,4-Diiodo-2,3,5,6-tetramethylbenzene (1.16 g, 3 mmol),5-(tributyltin)-2,2′-bithiophene (5.6 g, 12 mmol) obtained in Example 1,Pd(PPh3)4 (24.3 mg, 0.021 mmol) was added sequentially under a nitrogen atmosphere.Add 25 ml of DMF (N,N-dimethylformamide),Rapidly warmed to 130 C, the system refluxed for 16 h,The reaction was shut down, cooled to room temperature, extracted with deionized water and dichloromethane respectively. The obtained organic phase was dried over anhydrous MgSO 4 and then purified by column chromatography. The stationary phase was 300 mesh silica gel and the mobile phase was dichloromethane. / petroleum ether (1:5), collecting the eluent containing the target product to evaporate the solvent,Obtaining 1.04 g of a yellow solid benzene-methyl-dithiophene derivative in a yield of 90%
