以4,4 ′-二叔丁基-2,2 ′-联吡啶和三氟甲磺酸钪(III)为原料,乙腈为溶剂,乙醚为沉淀剂,合成了4,4 ′-二叔丁基-2,2 ′-联吡啶三氟甲磺酸盐。通过FT-IR、1H、13 C {1H}和19 F {1H} NMR和CHN元素分析对新化合物的结构进行了表征。这是一种不直接使用三氟甲磺酸而获得单质子化联吡啶鎓三氟甲磺酸盐的安全而简单的方法。
4,4′-Di-tert-butyl-2,2′-bipyridinium trifluoromethanesulfonate was synthesized by stirring 4,4′-Di-tert-butyl-2,2′-bipyridine with scandium(III) trifluoromethanesulfonate in acetonitrile, followed by precipitation with diethyl ether. The structure of the new compound was characterized by FT-IR, 1H, 13C{1H} and 19F{1H} NMR spectroscopy and CHN elemental analysis. This is a safe and simple method to obtain mono-protonated bipyridinium trifluoromethanesulfonate without the direct use of trifluoromethanesulfonic acid.
