Abstract: The p-alkoxybenzaldehydes are key intermediates for synthesis of liquid crystalline materials. This paper reports a new method for synthesizing p-alkoxybenzaldehydes from sodium p acylphenolate with n-alkyl bromide or chloride at certain temperature in EtOH. By using this method, some compounds have been obtained in good yield. Some synthetic routes are illustrated and evaluated.

Key words: p-alkoxybenzaldehydes, Willamson synthesis for ether, Cannizzaro reaction
