Main‐Group Chemistry The germanium awakens in the field of bis(pentafluoroethyl)germanes. Employing the phenyl group as a protecting group opens a straightforward synthetic route to (C 2 F 5 ) 2 GePh 2 . To obtain functionalizable bis(pentafluoroethyl)germanes, the deprotection can be effected with gaseous HBr or HCl under the assistance of a Lewis acidic catalyst. The derivatization of the obtained halogenogermanes is described by the reactions with Ag 2 CO 3 to obtain hexakis(pentafluoroethyl)trigermoxane and with Bu 3 SnH yielding (C 2 F 5 ) 2 GeH 2 , studied by X‐ray diffraction. The complete story can be found in the Full Paper by B. Hoge and colleagues on page 4758 ff.
