  Nouveaux procédés de préparation des isocyanates F-alkylés linéaires ou ramifiés à partir des iodures de 2-F-alkyléthyle

  摘要：

  Isocyanates are extremely versatile compounds in organic synthesis, but their synthesis is not easy. One of the most convenient methods uses acids as intermediates. In the F-alkyl series, it is sometimes difficult to obtain them by a general way. We have managed an efficient synthetic route to F-alkyl acids through malonates from 2-F-alkylethyl iodides.

  Superhydrophobic and oleophobic surfaces containing wrinkles and nanoparticles of PEDOT with two short fluorinated chains

  摘要：

  通过电沉积含有两条短氟化链的原始 PEDOT 衍生物，可获得超疏水性和疏油性表面。这种憎液特性是由于两条氟化链的存在使聚合物具有较高的固有疏水性和疏油性，以及电沉积过程中形成的皱纹和球形颗粒。褶皱和球形颗粒的存在以及由此产生的表面疏水性和疏油性与氟化链长度和电化学参数（恒定电位沉积时的沉积电荷以及循环伏安法沉积时的扫描速率和扫描次数）相关。在这里，皱纹和球形颗粒数量的增加会导致表面粗糙度的增加，尤其是表面疏水性的增加，而表面疏油性并不总是受到影响。不过，通过仔细选择电化学参数，也有可能增加表面疏油性。这项研究还可以制备氟含量低的超级憎液表面（生物累积潜力低的材料）。

  The replacement of iodide in 2-perfluoroalkyl-1-iodoethanes by anions derived from dialkyl malonate affords α-(2-perfluoroalkyl)ethyl malonic esters in high yields with negligible elimination and dialkylation, using bases such as K2CO3 or NaH in THF. The physical properties of the products are described.

  An easy synthetic procedure in two or three steps from perfluoroalkylethyl iodide derivatives led to six novel fluorinated carboxylates monomeric and gemini surfactants with one or two hydrophobic tails, respectively: R-F(C2H4)CH(CO2-)(2),2Na(+) and [RF(C2H4)](2)C(CO2-),Na+, where R-F = C4F9, C6F13, and C8F12. These anionic surfactants exhibited very low surface tension from 15 to 33 mN/m as well as low critical micelle concentration until 1.3 x 10(-4) mol/L. Furthermore, the surface properties of the gemini compound with two short fluoroalkyl chains (R-F = C4F9) were found to be almost equal to those of the monomeric surfactant with one long fluoroalkyl chain (R-F = C8F17), which could provide an interesting alternative to the bioaccumulative long-chain perfluorinated surfactant.
• A General Approach to Biocompatible Branched Fluorous Tags for Increased Solubility in Perfluorocarbon Solvents

  A modular, cost-effective route to a library of branched fluorous tags with two short, biocompatible, fluorinated chains (C6F13) is reported. These branched fluorous tags provide high fluorous content without the use of long-chain linear perfluorocarbons, which have rising health concerns due to their bioaccumulation. By attaching these tags to a porphyrin, it is demonstrated that high solubility can be achieved in fluorous solvents that are readily cleared from mammals. This work enhances the biocompatibility of perfluorocarbon nanoemulsions for photodynamic therapy.
