Reactions of 4-alkyl-2,6-di-tert-butylphenols containing OH, SH, COOH, and COOMe groups in their para substituents with hydrogen chloride and hydrohalic acids were studied. One-step transformations of 2,6-di-tert-butyl-4-(ω-hydroxyalkyl)phenols to the corresponding 4-(ω-halogenoalkyl)phenols, as well as of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid and its esters to phloretic acid were proposed
研究了在其对位取代基中含有 OH、SH、COOH 和 COOMe 基团的 4-烷基-2,6-二叔丁基苯酚与氯化氢和氢卤酸的反应。2,6-二叔丁基-4-(ω-羟烷基)苯酚一步转化为相应的4-(ω-卤代烷基)苯酚,以及3-(3,5-二-叔-提出了丁基-4-羟基苯基丙酸及其酯类植物草酸。4-(3-巯基丙基)苯酚与浓加热。HBr 缩合为 3-(4-羟基苯基) 丙基 4-(3-巯基丙基) 苯基硫醚作为主要产物。
