solvent‐ and catalyst‐free reaction of naphthalene with an excess of RFI reagent (RFCF3, C2F5, n‐C3F7, and n‐C4F9) was used for the first time to produce a series of highly perfluoroalkylated naphthalene products NAPH(RF)n with n=2–5. Four 95+ % pure 1,3,5,7‐NAPH(RF)4 with RFCF3, C2F5, n‐C3F7, and n‐C4F9 were isolated using a simple chromatography‐free procedure. These new compounds were fully characterized
高温气体相,用过量的R萘的溶剂和不含催化剂的反应˚F 1试剂(R ˚F CF 3,C 2 ˚F 5,Ñ -C 3 ˚F 7,和Ñ -C 4 ˚F 9)用于在第一时间以产生一系列高度全氟烷基化萘产品NAPH的(R ˚F)ñ与N = 2-5。四95+%纯1,3,5,7- NAPH(R ˚F)4,其中R ˚F CF 3,C 2 ˚F 5,使用简单的无色谱方法分离出n C 3 F 7和n C 4 F 9。这些新的化合物被充分表征由19 F和1个H NMR光谱,X-射线晶体学(对于R ˚F CF 3和C 2 ˚F 5),大气压化学电离质谱法,和环状和方波伏安法。DFT计算证实,拟议的合成方法产生了最稳定的异构体,而替代制备技术尚未获得该异构体。
