资源简介：
An intramolecular germylene-phosphine
Lewis pair (1) was reacted with germanium dichloride
to give in 92% yield a phosphine
adduct of a chloro substituted germyl-germylene (2).
After reduction of this dichloride with strong reductants like the
Mg(I) reagent {(MesNacnac)Mg}2 (72% yield) or
Na (52% yield) a phosphine stabilized digermavinylidene (3) was isolated as crystalline material [MesNacnac = {[(Mes)NC(Me)]2CH}−, Mes = 2,4,6-Me3C6H2]. The electronic structure of the digermavinylidene
was investigated by density functional theory calculations. In reaction
with adamantylphosphaalkyne the product of a [2+2] cycloaddition was
characterized (4). Adamantylazide abstracts at room temperature
a germanium atom from the digermavinylidene and a tetrameric organogermanium
nitride (5) was isolated as colorless crystals.
