Reaction Conditions:

Stage #1: 4,4′-bis-(n-octyl)-dithieno[3,2-b:2′,3′-d]silolwith n-butyllithium in tetrahydrofuran at -78; for 1 h;Inert atmosphere;
Stage #2: trimethyltin(IV)chloride in tetrahydrofuran at -78 - 20;Inert atmosphere;

Steps:

1.3 3) Synthesis of Compound 3:

Take a double-neck round bottom flask, anhydrous and anaerobic treatment, anhydrous tetrahydrofuran as solvent, nitrogen protectionAdd dithieno-silacyclopentane under the protection, add n-butyllithium at -78 ° C, stir at -78 ° C for one hour, then add trimethyltin chloride, return to room temperature and stir, reaction overnight, TLC monitoring After the reaction is completed, the reaction solution is quenched by adding a potassium fluoride solution, and the reaction solution is transferred to a separating funnel, and the organic phase is washed with dichloromethane and brine, and dried over anhydrous sodium sulfate. After concentration by pressure, the compound 3 is obtained as a yellow oil. The ratio of the dithienosilane, n-butyllithium, trimethyltin chloride and tetrahydrofuran is: dithienosilyl 1 weight Share:2.2 parts by weight of n-butyllithium: 2.4 parts by weight of trimethyltin chloride: 40 parts by volume of tetrahydrofuran, yield 95%;
