Reaction of Bis[bis(trimethylsilyl)methyl]germylene with Tris(4-tert-butylphenyl)methylium Ion: Formation of a Unique Germyl Cation Weakly σ-Coordinated to Aromatic Group
The reaction of bis[bis(trimethylsilyl)methyl]germylene with tris(4-tert-butylphenyl)methylium TPFPB− in toluene produced an unexpected germyl cation, {[(Me3Si)2CH]Me2Si}{[(4-tert-BuC6H4)3C]Me2Si}-HCMe2Ge+, which was formed through several consecutive rearrangements of the methyl, bis(trimethylsilyl)methyl, and triarylmethyl groups.
