monosubstituted products. Diethylphosphine, sodium benzenethiolate, lithium chloride, and lithium bromide give mainly 4,5-di- and 3,4,5,6-tetra-substituted products under the conditions described. The reaction with lithium chloride has also been applied to tetrafluorohydroquinone, and gives tetrachlorohydroquinone in high yield. Tetrafluorophthalonitrile reacts with arylamines and with polynuclear aromatic
二甲基甲酰胺,1-萘甲酸钠,苯胺,N-甲基苯胺和氨容易影响四氟邻苯二甲腈中4位氟离子的亲核取代,从而获得高收率的单取代产物。在所述条件下,二乙基膦,苯硫醇钠,氯化锂和溴化锂主要得到4,5-二-和3,4,5,6-四取代的产物。与氯化锂的反应也已经应用于四氟氢醌,并以高收率得到四氯氢醌。四氟邻苯二甲腈在低极性溶剂中与芳胺和多核芳香烃反应,生成稳定的结晶分子络合物。
