Sogar das elektropositive Element Silicium löst Elektronentransferprozesse in Amidobis(enolat)‐Komplexen aus: Dies belegen die Umsetzungen von Halogeniden RSiX 3 mit HN[CH 2 C(O) t Bu] 2 in Gegenwart einer Base. Bei kleinen Substituenten R erhält man die pentakoordinierten Komplexe 1 (R=H, Cl, Br, Ph), mit der sperrigeren t Bu 3 Si‐Gruppe den tetrakoordinierten Komplex 2 .
