Gas‐free generation of pentafluoroethyllithium : Perfluoroalkylation reactions are often characterized by the tedious handling of gases which lead to the development of numerous easy‐to‐handle perfluoroalkylation reagents. In the course of this the hypervalent [PPh 4 ][Sn(C 2 F 5 ) 5 ] represents an easily accessible, storable and solid precursor for the generation of the highly reactive LiC 2 F 5 . Its reactivity and the separation of tin‐containing byproducts were proven in pentafluoroethylation reactions. More information can be found in the Full Paper by B. Hoge et al. on page 1838.
