the [Al(OTeF5)4]– anion were studied by the synthesis and characterization of its tetraalkylammonium salts [NAlk4][Al(OTeF5)4] [Alk4 = –(CH3)4, –(C2H5)4, –(C2H5)3CH3, –(C3H7)4, –(C4H9)4]. The one‐pot synthesis includes formation of the Brønsted acid in 1,2–difluorobenzene, H[Al(OTeF5)4](solv.), and its reaction with [NAlk4]Cl [Alk4 = –(CH3)4, –(C2H5)4, –(C2H5)3CH3, –(C3H7)4, –(C4H9)4] to the corresponding
[Al(OTeF 5)4 ] -阴离子的弱配位性能通过其四烷基铵盐[NAlk 4 ] [Al(OTeF 5)4 ] [Alk 4 = –(CH 3)4, –(C 2 H 5)4,–(C 2 H 5)3 CH 3,–(C 3 H 7)4,–(C 4 H 9)4]。一锅法合成包括在1,2-二氟苯中形成布朗斯台德酸,H [Al(OTeF 5)4 ] (溶剂),以及与[NAlk 4 ] Cl [Alk 4 = –(CH 3)]的反应。4,–(C 2 H 5)4,–(C 2 H 5)3 CH 3,–(C 3 H 7)4,–(C 4 H 9)4 ]形成相应的盐。获得[N(C 4 H 9)的单晶4 ] [Al(OTeF 5)4 ]并通过X射线衍射分析表征。
