二芳基亚锗烷基Ge(Ar Me6)2和Ge(Ar i Pr4)2(Ar Me6 = C 6 H 3 -2,6-(C 6 H 3 -2,4,6-Me 3)2),Ar i Pr4= C 6 H 3 -2,6-(C 6 H 3 -2,6- i Pr 2)2)与乙烯可逆反应。结果表明,Ge(Ar i Pr4)2在空间上更拥挤。也可逆地结合丙烯。通过1 H和13 C NMR光谱表征了蓝宝石产物Ar 2 GeCH 2 CHR(Ar,R = Ar Me6,H(1a),Ar i Pr4,H(1b)和Ar i Pr4,Me(1c))。在1b的情况下通过X射线晶体学。乙烯下Ge(Ar i Pr4)2的热解导致Ge–C键均质化和Digermene [(Ar i Pr4)Ge(Et)] 2(1d)。反应的热力学参数通过可变温度1 H NMR光谱法确定。

whereas with H(2) the tetravalent hydride Ar'GeH(3) (4) was obtained with Ar'H elimination. In contrast, the reactions with the divalent Sn(II) aryls did not lead to Sn(IV) products. Instead, arene eliminated Sn(II) species were obtained. SnAr(#)(2) reacted with NH(3) to give the Sn(II) amide Ar(#)Sn(mu-NH(2))}(2) (5) and Ar(#)H elimination, whereas no reaction with H(2) could be observed up to 70

shown to react reversibly with ethylene. It is demonstrated that the more sterically crowded Ge(AriPr4)2 also reversibly binds propylene. The germirane products Ar2GeCH2CHR (Ar, R = ArMe6, H (1a), AriPr4, H (1b), and AriPr4, Me (1c)) were characterized via 1H and 13C NMR spectroscopy and by X-ray crystallography in the case of 1b. Thermolysis of Ge(AriPr4)2 under ethylene resulted in Ge–C bond homolysis
