Reaction Steps

To a stirred solution of 0.8 g (3 mmol) of 3-cyano-2,5-dithienylpyrrole (XVII) in 20 mL of dry THF was added 8 mL of a 1M solution of borane-tetrahydrofuran complex in THF. After the initial exothermic reaction subsided, the mixture was heated to reflux under an inert (argon gas) atmosphere overnight. The solvents then were evaporated in vacuo and the residue partitioned between CHCl3 and a 3N hydrochloric acid (HCl) solution. The CHCl3 layer then was extracted three times with 10 mL portions of 3N HCl dried over sodium sulfate, filtered, and concentrated in vacuo to give 410 mg of unreacted 3-cyanodithienylpyrrole (XVII).
