  Tetramesitylgermasilene: the first relatively stable germasilene and its rearrangement to a silylgermylene

  摘要：

  The thermolysis of hexamesitylsiladigermirane (1) in the presence of triethylsilane at 105-degrees-C yields mesityl(triethylsily)(trimesitylsilyl)germane (3) and dimesityl(triethylsilyl)germane (4) Photolysis of 1 at -78-degrees-C in the presence of triethylsilane gave tetramesitylgermasilene, which upon warming rearranged by a 1,2-aryl shift to mesityl(trimesitylsilyl)germylene, which was then trapped by the silane.

  The addition reactions of tetramesitylgermasilene with methyl vinyl ketone (MVK), crotonaldehyde, and acrylonitrile were studied. When tetramesitylgermasilene was allowed to react with MVK, [2 + 4] cycloaddition and nonregioselective carbonyl [2 + 2] cycloaddition products were isolated. When tetramesitylgermasilene was allowed to react with crotonaldehyde, the carbonyl [2 + 2] adduct was produced exclusively. The regiochemistry was not determined. The addition of acrylonitrile to tetramesitylgermasilene yielded a germasilacyclobutane, which is the formal [2 + 2] cycloadduct between the germasilene and the C-C double bond of acrylonitrile. Tetramesityldisilene was also found to yield a formal [2 + 2] adduct with acrylonitrile. However, tetramesityldigermene rearranges to a germylgermylene at a faster rate than acrylonitrile addition.
