  Hybrid surfactants containing separate hydrocarbon and fluorocarbon chains

  摘要：

  Two homologous series of double-tail hybrid surfactants containing a hydrocarbon chain and a fluorocarbon chain attached to the same hydrophilic head group have been synthesized. The micellar solutions of such hybrid surfactants have been studied by conductance, surface tension, F-19 NMR and H-1 NMR. The dependence of the cmc on the chain length follows Kleven's equation. The micellar aggregation numbers are 10-35 and become smaller as the chain length increases. When the hydrocarbon chain bears three carbons or more, both the fluorocarbon and the hydrocarbon chains are incorporated inside the micelle.

• The halogen-metal exchange reaction between perfluoro-n-heptyl iodide and n-butyllithium

  日期：1969.10

  diethyl ether/pentane undergo 40–50% halogen-metal exchange below −90° and form a stable heterogeneous system. The stability of the perfluoro-n-heptyllithium present is attributed to its association with perfluoro-n-heptyl iodide. Such a mixture reacts only slowly with acetaldehyde below −90° to give a low yield of 1-(perfluoro-n-heptyl)ethanol. Halogen-metal exchange is complete in the presence of a sufficient

  全氟正庚基碘和正丁基锂在乙醚或无卤的乙醚/戊烷中的1–1.5摩尔当量在-90°以下进行40–50％的卤素金属交换，并形成稳定的异质体系。存在的全氟正庚基锂的稳定性归因于其与全氟正庚基碘的缔合。这样的混合物仅在低于-90°的乙醛中缓慢反应，以产生低产率的1-（全氟-正庚基）乙醇。根据相对的碳负离子稳定性，在足够过量的氟代烷基碘的存在下，卤素-金属交换完成。在存在大量过量的正丁基锂的情况下，体系的稳定性大大降低，反式-1-正丁基三氟甲基氟-1-庚烯是主要产品。稳定的非均质混合物在上方变得均匀约-90°，并且在乙醛的存在下，氟代烷基锂经历快速反应以给出定量产率的氟代醇。全氟正庚基锂即使在-75°时也会非常迅速地分解，但是可以通过在适当的底物存在下进行生产而在更高的温度下使用。
