Sodium Carbonate → 1,4-Benzenedicarboxaldehyde, 2,5-dihydroxy-

Participants

Reaction Steps

0.5 g of 2,5-dimethoxybenzene-1,4-dicarboaldehyde (AD) and 25 mL of boron tribromide were dissolved in 150 mL of chlorobenzene and stirred at room temperature for 12 hours. After complete reaction, the reacted mixture was neutralized with sodium carbonate, followed by extraction with water and dichloromethane and recrystallization within dichloromethane, thereby obtaining 2,5-dihydroxybenzene-1,4-dicarboaldehyde. The obtained product exhibited yield, property and NMR analysis result as follows.
