Alternativ-liganden : XI. Neue chelatliganden des typs Me2XGeMe2(CH2)2X'Me2(X,X'N, P und/oder As)

Abstract Starting from germanium metal, chelating ligands of the type Me 2 XGeMe 2 -(CH 2 ) 2 X'Me 2 (MeCH 3 ;X,X'N,P,As) have been prepared via the intermediates Me 2 GeCl 2 , Me 2 NGeMe 2 Vi, ClGeMe 2 Vi, and ClGeMe 2 (CH 2 ) 2 X'Me 2 , using a combination of different synthetic routes. The new compounds have been characterized by analytical and spectroscopic (IR, NMR, mass spectral) methods.
