For (pentafluoroethyl)phenylstannanes, (C2F5)4−n SnPhn (n=1–3), and dimethylbis(pentafluoroethyl)stannane, (C2F5)2SnMe2, a high yield synthesis was developed by the use of LiC2F5 as a C2F5 transfer reagent. The treatment of these products with gaseous hydrogen chloride or hydrogen bromide afforded (C2F5)4−nSnXn (X=Cl, Br; n=1–3) in good yields. The (pentafluoroethyl)stannanes were fully characterized
对于(C 2 F 5)4- n SnPh n(n = 1–3)和二甲基双(五氟乙基)锡烷(C 2 F 5)2 SnMe 2(五氟乙基)苯基锡烷,通过使用使用LiC 2 F 5作为C 2 F 5转移试剂。用气态氯化氢或溴化氢处理这些产物,得到(C 2 F 5)4- n SnX n(X = Cl,Br; n= 1–3)。(五氟乙基)锡烷通过1 H,13 C,19 F和119 Sn NMR,IR光谱和质谱进行了全面表征。用1,10-菲咯啉(phen)处理(五氟乙基)卤化锡(C 2 F 5)4- n SnX n导致形成相应的八面体配位配合物[(C 2 F 5)4- n SnX n(phen)],其结构通过X射线衍射分析得以阐明。
