摘要: 在低温碱性甲醇溶液中一氯化四苯基卟啉铁催化萘酚H2O2氧化高选择性地制取2-羟基-1,4-萘醌(HNQ),以2-萘酚和1-萘酚为底物时HNQ的最高产率分别为57%和40%(纯度>95%).根据金属卟啉催化氧化反应的特性,采用UV-Vis和EPR现场光谱监测催化剂和反应物的光谱变化,提出了羟基游离基加成反应机理.

关键词: 金属卟啉催化作用机理, 萘酚, 2-羟基-1, 4-萘醌

Abstract: With hydrogen peroxide as oxidant, we got a high selectivity of 2-hydroxy-1,4- naphthaqinone from 1- and 2-naphthol in methanol solution containing sodium hydroxide at low temperature. A series of tetraphenylporphyrin ferron chloride and its corresponding substitutes are employed as catalysts. By determination of UV-Vis and EPR spectra in situ, a probable mechanism model was established.

Key words: Catalysis mechanism of metalloporphyrin, Naphthol, 2-Hydroxy-1,4-naphthaqinone
