The synthesis of novel heteroleptic germanium(II) compounds starting from [2,4-di-tert-butyl-6-((dimethylamino)methyl)phenyl]germanium chloride, MamxGeCl (1), is reported. 1 reacts with potassium alkoxides to give the alkoxy-substituted compounds MamxGeO-t-Bu (2), MamxGeO-i-Pr (3), MamxGeOEt (4), and MamxGeOMe (5). The ethynyl-substituted species MamxGe(C⋮CPh) (6) and MamxGe(C⋮CH) (7) are obtained by the reaction of 1 with LiC⋮CPh and NaC⋮CH, respectively. The alkyl-substituted germanium(II) species MamxGeR (R = t-Bu (8), n-Bu (9), Me (10)) are formed by the reaction of 1 with the corresponding alkyllithium compounds. Derivatization of 8−10 with MeI leads to the formation of compounds containing the germyl cations [MamxGe(t-Bu)(Me)]+ (11a), [MamxGe(n-Bu)(Me)]+ (12a), and [MamxGe(Me)2]+ (13a), respectively. All new species have been characterized by NMR, MS, and microanalytical data. X-ray crystal structure determinations are presented for 3, 4, 6, 7, and 11.
