  Perfluoroalkyllithiums were effectively generated from perfluoroalkyl halides in the presence and absence of electrophiles using flow microreactor systems. The in situ trapping with electrophile is conducted at much higher temperatures than those required for batch macro reactors. The subsequent trapping method is quite effective for highly reactive electrophiles that are not compatible with the lithiation process.

  全氟烷基锂通过使用微流反应器系统在有无电亲体的情况下有效地从全氟烷基卤化物中生成。与批量宏反应器所需的温度相比，原位捕获电亲体的温度要高得多。随后的捕获方法对于与锂化过程不兼容的高反应性电亲体非常有效。

  The 19F nuclear magnetic resonance spectra of a variety of fluorocarbon derivatives of metals are reported. A large shift to low field is found for the absorption by a CF2 group bonded directly to manganese, rhenium, iron, or cobalt. When a carbonyl group is interposed between the transition metal and the CF2 group, or when a CF2 group is bonded to tin or phosphorus, no large shifts of the fluorine resonances to low fields are observed. It is suggested that these magnetic screening effects are related to the presence in the transition metal derivatives of low-lying excited states in the bonds between the metals and the carbon atoms of the α—CF2 groups, with the result that the paramagnetic contribution to the screening constants of the fluorine nuclei is substantially increased.
