A synthesis of perfluoro[2.2]paracyclophane has been sought ever since the partially fluorinated octafluoro[2.2]paracyclophane (AF4) was prepared and its chemistry studied. This compound has now been prepared in 39% yield from the precursor, 1,4-bis(chlorodifluoromethyl)-2,3,5,6-tetrafluorobenzene by its reaction with Zn when heated in acetonitrile at 100 °C. Two preparations of the precursor, first
自从制备了部分氟化的八氟[2.2]对环环烷(AF4)并对其化学进行了研究以来,一直在寻求全氟[2.2]对环环烷的合成。现在,当在100°C的乙腈中加热时,通过与Zn反应,可以从前体1,4-双(氯二氟甲基)-2,3,5,6-四氟苯以39%的产率制备该化合物。还描述了两种前体制备方法,分别是从1,4-二氰基-2,3,5,6-四氯苯和从1,2,4,5-四氯苯开始的改进方法,这是与我们相关合成方法的关键比较AF4。
