Heavy Phenyllithium and -sodium: Synthesis and Characterization of Germanium Analogues of Phenyl Anion ('Germabenzenyl Anions')
The heavier phenyl anion analogues, 2-tert-butylgermabenzenyllithium Li+center dot 1(-) and sodium Na+center dot 1(-), were synthesized via aryl elimination from the corresponding 1-Tbt-2-tert-butylgermabenenze 3 (Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl). The properties of Li+center dot 1(-) and Na+center dot 1(-) have been elucidated spectroscopically, and structural determination of Na+center dot 1(-) was performed using X-ray diffraction analysis.
