  摘要：

  一系列二卤代和五个四氯偶氮苯在冰乙酸中使用30％的过氧化氢氧化，反应在60-70℃下进行24小时，得到相应的偶氮氧化物。如预期，通常从2,2'-位置含有取代基的偶氮苯中获得的产量较低，而从3,3'-和4,4'-位置含有取代基的化合物中获得的产量则非常好。

  Aromatic azoxy compounds have wide applications and they can be prepared by stoichiometric or catalytic reactions with H2O2 or N2H4 starting from anilines or nitroarenes. In this work, we will present the direct chemoselective hydrogenation of nitroarenes with H2 to give aromatic azoxy compounds under base-free mild conditions, with a bifunctional catalytic system formed by Ni nanoparticles covered

  A study has been made of the reduction of substituted nitro compounds by magnesium in methyl alcohol. Some nitro compounds smoothly reduce to the corresponding azoxy compounds, while others yield a complex mixture of azo, azoxy, and other compounds. An investigation has been made of the various factors affecting the velocity of the reaction and the relative proportion of the products. An attempt is

  The synthesis of the azoxybenzenes by the reduction of nitroarenes with reducing agent potassium borohydride in water was reported for the first time. PEG-400 was used as a phase transfer catalyst and could effectively catalyze the reduction. The electronic effects of substituent groups play an important role in determining the reduction efficiencies. Electron-withdrawing substituents promote the formation

  This invention relates to a novel diamine having a perfluorodiimide for the manufacture of a new fluorine-containing polyimide film, a method for preparing the same, and the new fluorine-containing polyimide film having a perfluorodiimide. The polyimide film prepared from the novel diamine having a perfluorodiimide side group according to the present invention includes a perfluorodiimide side group, thereby reducing the intermolecular CTC effect by including the perfluorodiimide side group, enhancing optical transparency due to the steric hindrance effect and inductive effect (electronegativity effect of diamine), improving solubility, increasing hydrophobicity, and exhibiting properties such as low moisture absorption and low dielectric constant, so it can be effectively used as a substitute for conventional polyimide films.
