Abstract
GeCl2·dioxane reacts with 1 and 2 equiv of [2,4-di-tert-butyl-6-(tert-butoxymethyl)phenyl]lithium (t-BomxLi) to give the germanium(II) compounds t-BomxGeCl (1) and [t-Bomx]2Ge (2), respectively. Reaction with 2 equiv of [2,4-di-tert-butyl-6-(iso-propoxymethyl)phenyl]lithium (i-PomxLi) affords [i-Pomx]2Ge (3). Compounds 1−3 show intramolecular coordination of the alkoxy ligand to the germanium(II) center. The use of the 2,4-di-tert-butyl-6-(methoxymethyl)phenyl ligand (Momx) does not lead to the expected base-stabilized germanium(II) species Momx2Ge but gives the germanium(IV) compound MomxGe[OCH2-(2,4-di-tert-butylphenyl)](Me) (4) as the result of an intramolecular O−CH3 bond oxidative addition process; X-ray crystal structure determinations are presented for 1, 2, and 4.
