Reaction Steps
In a three-neck flask, 100 ml in inner volume, made of glass and provided with a stirrer, 4.0 g (30 mmols) of terephthal aldehyde and 30 g of dichloromethane were placed. The reactants, after having added 8.1 g (75 mmols) of 1,3-propane dithiol, were stirred continuously at 25° C. for 20 minutes and, after having subsequently added 6.3 ml (50 mmols) of a boron trifluoride diethyl ether complex, further stirred continuously at 25° C. for two hours, to form a white precipitate. The resultant white precipitate was filtered, to obtain 6.6 g (70% in yield) of 2,2′-(1,4-phenylene) bis-1,3-dithian (hereinafter referred to as “Intermediate (3)”).
