Abstract

1. The PMR method enables the state of the ion pairs in the compounds Et₃GeM (M=Li, Na, K, Rb, Cs) to be monitored from the change in the value of the internal chemical shift Δ of the protons of the ethyl group. 2. 2,2-Dimethylbutan-3-one reacts with Et₃GeM with formation of the carbinol Et₃Ge(tBu)MeCOH or the ambidentate enolate-anion [t-BuCOOH₂]^-M⁺, which is determined by the nature of the cation M and the solvent. 3. The transmetallation reaction has been studied of the compounds Et₃GeM and Et₃SiM, which is based on the replacement of a less electropositive alkali metal M by a more electropositive metal.
