compounds, allyl functionalities, vinyl phenyl moieties, trifluoromethyl (CF3) groups, etc. were prepared by nucleophilic substitution reaction of 2,3,4,5,6-pentafluorobenzonitrile (PFBN) in a stepwise manner at room temperature in dipolar aprotic solvents in a regioselective manner. Mono substituted aryl ether further underwent two more substitutions at ortho and ortho′ positions either with the same or
官能芳基醚轴承单-和二-取代的偶氮化合物,烯丙基官能团,乙烯基苯基部分,三氟甲基(CF 3)基团等。由2,3,4,5,6-五氟的亲核取代反应来制备(PFBN)在以区域选择性的方式在偶极非质子溶剂室温以逐步的方式。单取代芳基醚在进一步接受两次多个取代邻位和邻位的'用相同的或不同的酚位置。然而,对位取代的单酯以及对-ether-邻通过使用羧酸盐作为亲核试剂没有进行任何进一步的移动(的一个) - 酯获得。的合成策略此处描述是用于进行各种功能材料,如润滑剂,液晶,固化剂,颜料和超疏水材料是有用的。
