全氟联苯是通过将联苯分子结构中的所有氢原子替换为氟原子而获得的一种化合物。它具有极强的化学惰性,几乎不溶于任何化学试剂,并且具备优异的耐低温性能、低表面能、高热稳定性和高绝缘性等特性。然而,这种独特的分子结构也导致全氟联苯熔体粘度较高,无法通过传统的熔融加工方法进行成品制备。
应用全氟联苯广泛应用于石油化工、微电子制造、机械制造以及航空航天等领域。在汽车工业中,随着汽车产业的快速发展,全氟联苯被广泛应用在汽车发动机输油软管和密封材料的合成中。此外,许多氟涂料以全氟联苯作为基体,包括PTFE涂料、常温固化型PEVE氟碳涂料和PVDF氟碳涂料等。这些材料广泛应用于建筑行业、海洋防污以及光纤涂料等领域。
合成方法将CuBr·SMe2(0.0013 g,0.0060 mmol)加入4 mL烘干小瓶,并用橡胶隔膜密封。三次用氩气置换后,再依次添加无水THF(0.60 mL)、苯乙炔基溴化镁(1.0 M in THF)(0.30 mL,0.30 mmol)和(环己基甲基)溴化镁,并搅拌混合物。随后向搅拌的混合物中添加二叔丁基二嗪酮(1)(0.0562 g,0.33 mmol)。在氩气氛围下室温搅拌3小时后,浓缩并通过快速色谱法(硅胶、戊烷)纯化。最终得到无色油状交叉耦合产物4g(81%),以及白色固体全氟联苯(58%)。其熔点为112-113°C(升熔点116-118°C),红外光谱(纯态)在1607, 1483, 1249, 979 cm-1,1H核磁共振(300 MHz,CDCl3)δ 7.40-7.33 (m, 2H),7.05-6.99 (m, 2AH),3.87 (s, 3H),以及19F核磁共振(282 MHz,CDCl3)δ -143.7 (dd, J F=23.1, 7.9 Hz, 2F),-156.6 (t, J F=20.9 Hz, 1F),-162.6 (td, J F=23.1, 7.9 Hz, 2F。HRMS计算值:C13H7F5O+的理论值为274.0412,实测值为274.0409。
