Procedure

NaBH4 (10 mg) was added to a THF solution (2 mL) containing 2,5″-diformyl-5,2′:5′,2″-terselenophene (15 mg) and stirred at room temperature for 5 h. The reaction solution was diluted with ethyl acetate (50 mL), washed with 2N HCl (5 mL), and washed with H2O (3×100 mL). The organic layer was separated, dried over MgSO4, filtered, and the solvent was removed under vacuum. The residue was chromatographed over silica gel using (1:1) hexanes/ethyl acetate to afford 2,5″-dihydroxymethyl-5,2′:5′,2″-terselenophene in 98% yield.
