摘要
An electronic chameleon: The planar cyclogermylene 1 can be described by the resonance structures 1A and 1B. It is accessible in 79% yield by dehydrohalogenation of the corresponding (β-diketiminato)chlorogermylene by LiN(SiMe3)2. Although the contribution of the dipolar resonance structure 1A is relatively small, its influence is seen in the transformations of 1 with Me3SiOTf or 1,2-dibromoethane. R = 2,6-diisopropylphenyl.
