以金刚烷胺为起始反应物, 首先在过量甲酸存在下, 与甲醛发生埃斯韦勒-克拉克甲基化反应合成了N,N-二甲基金刚烷叔胺, 在此基础上通过N,N-二甲基金刚烷叔胺与氯乙酸钠、溴代正丁烷、溴代正辛烷、溴代十二烷、溴代十六烷等一系列季铵化试剂的季铵化反应, 分别合成了N,N-二甲基金刚烷甜菜碱型表面活性剂及N-(1-金刚烷基)-N,N-二甲基正丁基溴化铵、N-(1-金刚烷基)-N,N-二甲基辛基溴化铵、N-(1-金刚烷基)-N,N-二甲基十二烷基溴化铵、N-(1-金刚烷基)-N,N-二甲基十六烷基溴化铵等金刚烷季铵盐阳离子型表面活性剂, 产率分别为75%, 75%, 61%, 44%, 54%. 采用元素分析, IR, 1H NMR等分析手段对5种产物进行了结构鉴定, 测试了各种金刚烷表面活性剂水溶液的表面张力.

N-(1-Adamantyl)-N,N-dimethylamine was synthesized by Eschweiler-Clarke methylation reaction of 1-adamantine and formaldehyde in presence of excess formic acid firstly. Then five adamantane-based surfactants, including N-(1-adamantyl)-N,N-dimethyl-betaine, N-(1-adamantyl)-N,N-dimethyl- butyl-1-ammonium bromide, N-(1-adamantyl)-N,N-dimethyloctyl-1-ammonium bromide, N-(1-adamantyl)- N,N-dimethyldodecyl-1-ammonium bromide and N-(1-adamantyl)-N,N-dimethyl-hexadecyl-1-ammonium bromide were prepared via quaternarization reactions of N-(1-adamantyl)-N,N-dimethylamine with the sodium chloroacetate, 1-bromobutane, 1-bromooctane, 1-bromododecane and 1-bromohexadecane, respectively. The structures of products were identified by elemental analysis, IR, 1HNMR, etc.

Key words: adamantane, quaternary ammonium, surfactant, synthesis
