资源简介：
The germylone dimNHCGe
(5, dimNHC = diimino N-heterocyclic
carbene) was successfully prepared via the reduction of the germanium
cation [dimNHCGeCl]+ with KC8. The molecular
structure of 5 was unambiguously established by both
NMR spectroscopy and single-crystal X-ray diffraction. The reactivity
of 5 was investigated, revealing that it undergoes oxidative
addition of HCl, CH3I, and PhI, accompanied by an unusual
migration of the H, Me, and Ph groups from germanium to the carbene
ligand. Related chemistry was also observed with C5F5N, which results in the migration of the fluorinated pyridine
moiety to the carbene ligand. Compound 5 also undergoes
cycloaddition with tetrachloro-o-benzoquinone to
afford a Ge(IV) adduct.
