Sodium borohydride → 4,5 Dihydroxymethyl-2,2': 5',2"-terthiophene

Participants

Reaction Steps

To a solution of 4-formyl-5-hydroxymethyl-2,2':5', 2"-terthiophene (0.1 g) in methanol (10 ml) was added excess amount of sodium borohydride. The reaction mixture was stirred at room temperature for 40 minutes. Methanol was removed and water was added.
