Regioselectivity in the -dialkylaminomethylation of phenols is greatest, for example in reactions of 2,5-dimethylphenol, when a mixture of the phenol and sulphur dioxide is allowed to stand for several hours before the addition of a bis-(dialkylamino)methane (aminal) or an alkoxydialkylaminomethane (aminol ether).
苯酚的-二烷基氨基甲基化反应中的区域选择性最大,例如在2,5-二甲基苯酚的反应中,在添加双-(二烷基氨基)甲烷(缩醛胺)之前,应让苯酚和二氧化硫的混合物静置几个小时。 )或烷氧基二烷基氨基甲烷(氨基醚)。
