[0131] 2,7-bis(tributylstannyl)-benzo[2,1-b; 3,4-b']dithiophene-4-carboxylic acid (2- Preparation of octyldodecyl) ester
[0132]
[0133] Into a 250 ml flask equipped with magnetic stirring, the following items were charged in the following order under argon flow: benzo[2,1-b; 3,4-b']dithiophene obtained as described in Example 1 - (2-octyldodecyl) 4-carboxylate (1.029 g; 2 mmol) and anhydrous tetrahydrofuran (THF) (Aldrich) (60 ml): the reaction mixture was cooled to -78° C. Stirring is maintained for about 10 minutes. Subsequently, 4.4 ml of lithium diisopropylamide solution (LDA) (Aldrich) 1.0 M was added dropwise to a mixture of tetrahydrofuran (THF) (Aldrich) / n-hexane (Aldrich) (1 / 1, v / v) (0.471 g; 4.4 mmol): The reaction mixture was kept under stirring at -78°C for 3 hours. Subsequently, 0.678 ml of tributyltin chloride (Aldrich) (1.627 g; 5 mmol) was added dropwise: the reaction mixture was kept under stirring at -78° C. for 30 minutes, then warmed to room tem...
Embodiment 3
[0135] Preparation of octyl 2-bromothiophene-3-carboxylate having formula (A)
[0136]
[0137] In a 100 ml flask equipped with coolant and magnetic stirring, the following items were charged in the following order under argon flow: 2-bromo-3-thiophenecarboxylic acid (Aldrich) (2.07 g; 10 mmol), N,N'-di Cyclohexylcarbodiimide (DCC) (Aldrich) (1.032g; 5mmol), 4-(dimethylamino)pyridine (DMAP) (Aldrich) (0.305g; 2mmol), anhydrous dichloromethane (DCM) (Aldrich ) (20 ml), after 5 minutes, 1-octanol (Aldrich) (1.302 g; 10 mmol) (Aldrich) was added dropwise: the reaction mixture was kept under stirring at room temperature (25° C.) for 24 hours. The reaction mixture was then placed in a 500ml separatory funnel, diluted with distilled water (150ml) and extracted with dichloromethane (DCM) (Aldrich) (3 x 100ml) to obtain aqueous and organic phases. The entire organic phase (obtained by combining the organic phases from three extractions) was dried over sodium sulfate (Aldrich) an...
