bismethylsilicon carbodi-imides have been prepared in high yield by halide metathesis reactions with lead(II), silver(I), or silicon(IV) species. The new derivatives in the series of general formula (MenH3 –nMN:)2C (MSi or Ge; n= 1, 2 or 3) have been characterised by 1H n.m.r., i.r., and Raman spectroscopy as well as mass spectrometry and cleavage reactions. The utility of the germanium carbodi-imides as synthetic
通过与铅(II),银(I)或硅(IV)物种进行卤化物易位反应,可以高收率制备双甲基锗和双甲基硅碳二亚胺。通式(Me n H 3 – n MN :)2 C(M Si或Ge;n = 1、2或3)系列中的新导数的特征是1H nmr,ir和Raman光谱以及质谱和裂解反应。第六种锗原子容易裂解Ge-N键,导致硫属锗烷及其相关衍生物的形成(Me n H 3 – n葛)2 E(E = O,S,Se或Te)和Me ñ ħ 3 - ñ GESR(R = Me中,卜吨,pH值,的MeC(O),或-CH 2 CH 2 - )。比较研究表明,在碳碳化二亚胺硅中,Si-N键不易受较重的硫属元素醇分解的影响。
