WebThe aryl aldehyde is less reactive than an aliphatic aldehyde. Consequently, the aryl aldehyde is less likely to react with free amines to form a Schiff base. Moreover, a Schiff base between an aryl aldehyde and a free amine is easily reversed. This means that the aldehyde is free to react with a hydrazide or oxyamine group.
