A series of quaternary alkylammonium sulfobetaines of general formula RN+(CH3)2(CH2)nSO3 -, where n = 2-4, have been synthesised by reacting the corresponding N,N-dimethylamines with either sodium 2-chloroethanesulfonate (n = 2), 1,3-propanesultone (n = 3), or 1,4-butanesultone (n = 4). Full details of the preparation of the required N,N-dimethylamines are reported.
一系列四级烷基铵阳离子硫苯甲酸盐,通用公式为 RN+(CH3)2(CH2)nSO3−,其中 n = 2-4,通过将相应的 N,N-二甲基胺与氯乙烷磺酸钠(n = 2)、1,3-丙烷磺内酯(n = 3)或 1,4-丁烷磺内酯(n = 4)反应合成。有关所需 N,N-二甲基胺的制备的完整细节已报告。
