Abstract1-Methylimidazolium hydrogensulfate, [Hmim][HSO4], a Brønsted acidic room temperature ionic liquid, is used as a catalyst and reaction medium for facile and eco-friendly deprotection of methoxymethyl (MOM) and ethoxymethyl (EOM) ethers to their corresponding alcohols under thermal conditions (Δ) and microwave irradiation (MW). Furthermore, one-pot interconversion to the respective acetates and
摘要布朗斯台德酸性室温离子液体1-甲基咪唑硫酸氢盐[Hmim] [HSO 4 ]被用作催化剂和反应介质,可对甲氧基甲基(MOM)和乙氧基甲基(EOM)醚进行简便且环保的脱保护醇在热条件(Δ)和微波辐射(MW)下。此外,还实现了一锅转化为各自的乙酸酯和三甲基甲硅烷基(TMS)醚。 图形概要
