Phenols (pKa = 10) are considerably more acidic than ordinary alcohols (pKa = 16-18) because the conjugate base (called a phenolate) is resonance stabilized. Since sodium hydroxide is the conjugate base of water (pK a = 15.7), the deprotonation of vanillin will

Remarque : il existe une écriture simplifiée de Reichstein qui repose sur le fait de ne pas écrire les atomes de C, O et H qui se situent entre les deux extrémités de la molécule et ceux qui ne forment pas la fonction cétone des cétoses.
