Reactions of 2,6-dialkylphenols with N-(N′,N′-diethylaminomethyl)phthalimide gave the corresponding 4-phthaloylmethylphenols, in which the phthaloyl group can be replaced by an alkylsulfanyl substituent via reactions with thiols. Phthaloylmethylphenols containing the tert-butyl groups that are ortho to the OH group can undergo acid-catalyzed de-tert-butylation.
2,6-二烷基苯酚与N-(N',N'-二乙基氨基甲基)邻苯二甲酰亚胺反应得到相应的4-邻苯二甲酰甲基苯酚,其中邻苯二甲酰基可以通过与硫醇反应被烷基硫烷基取代基取代。含有与 OH 邻位的叔丁基的邻苯二甲酰甲基苯酚可以进行酸催化的脱叔丁基化。
