Efficient Transformation of Alcohols in Fluorinated Ionic Liquids as Unique Reaction Media

我们成功合成了四种咪唑环氮原子上带有多氟芳基的新型咪唑盐，并对其物理性质进行了初步研究。此外，我们试图将上述盐作为一种独特的缺电子NHC配体应用于某些过渡金属催化。另一方面，为了简明地获得含有多氟芳基的多用途分子，我们开发了一种新的合成方法，通过铜催化多氟芳烃与丙炔磷酸盐的区域选择性直接偶联制备（多氟芳基）烯。

We succeeded in the synthesis of four novel imidazolium salts that bear polyfluoroaryl groups on the nitrogen atom of the imidazolium ring and preliminary investigated their physical properties. Additionally, we attempted to apply the above salts to some transition metal catalysis as a unique electron-deficient NHC ligand. On the other hand, to get a concise access to versatile molecules that contain the polyfluoroaryl groups, we developed a new synthetic method for preparation of (polyfluoroaryl)allenes by copper-catalyzed regioselective direct coupling of polyfluoroarenes with propargylic phosphates.
