A new synthetic way is described to prepare 4-trimethylammonio-2,2,6,6-tetramethylpiperidine-1-yloxyl bearing tetrafluoroborate, hexafluorophosphate or bis(trifluoromethylsulfonylimide) by an anion metathesis of 4-trimethylammonio-2,2,6,6-tetramethylpiperidine-1-yloxyl iodide using the corresponding silver salts. 4-Trimethylammonio-2,2,6,6-tetramethylpiperidine-1-yloxyl iodide is obtained by the methylation
描述了一种新的合成方法,该方法通过4-三甲基铵-2,2,6,6的阴离子复分解制备带有四氟硼酸根,六氟磷酸根或双(三氟甲基磺酰亚胺)的4-三甲基铵-2,2,6,6-四甲基哌啶-1-基氧基。 -四甲基哌啶-1-基氧碘化物,使用相应的银盐。通过将4-氨基-2,2,6,6-四甲基哌啶-1-基氧基与甲基碘甲基化获得4-三甲基铵-2-,2,6,6-四甲基哌啶-1-基氧基碘。新的自旋探针4-三甲基铵2,2,6,6-四甲基哌啶-1-基氧基双三氟甲基磺酰亚胺和含有四氟硼酸根或六氟磷酸根的自旋探针可用于有效研究具有相似阴离子的离子液体。
