卤素取代甲苯的合成及其在Co（OAc）_2－Mn（OAc）_2－NaBr催化下的液相氧化反应

Synthesis of Halogenated Toluenes and Its Liquid Phase Oxidation with Co (OAc)_2-Mn (OAc )2-NaBr

合成了３－氟甲苯和另外５个氯或溴取代的３－氟甲苯，以Ｃｏ（ＯＡｃ）２·４Ｈ２Ｏ、Ｍｎ（ＯＡｃ）２·４Ｈ２Ｏ和ＮａＢｒ为催化剂用液相氧化反应将其氧化为相应的卤代苯甲酸。该反应产率较高，所得卤代苯甲酸纯度好．６个卤代的３－氟甲苯及６个相应的卤代苯甲酸其结构经ＩＲ、ＵＶ、１ＨＮＭＲ、ＭＳ和元素分析所确证。

Fluorotoluene and halogenated 3-fluorotoluenes have been synthesized and oxidized by Co(OAc)2-Mn(OAc)2-NaBr system to the corresponding carboxylic acids in liquid phase with good yields. All the compounds are characterized by UV, IR, 1H NMR, MS spectrometry and elemental analysis.
