    Description / Table of Contents: Formation and Structures of N-(tri-t-butoxysilyl)aniline CompoundsPara-substituted N-(tri-t-butoxysilyl)anilines (t-BuO)3SiNRC4H4X-p, R = H, CH3, with substituents of high electron affinity (X = CN, NO2) were prepared by a one-pot reaction of tri-t-butoxychlorsilane, potassium t-butanolate and substituted anilines. Corresponding compounds with substituents of low electron affinity (X = OMe, H) preferably were prepared by metalation of anilines with sodium amide. Four crystal structures were determined. N-(tri-t-butoxysilyl)-p-nitro-aniline, N-methyl-(N-tri-t-butoxysilyl)-p-nitroaniline and N-(tri-t-butoxysilyl)-p-cyanoaniline crystallize at 298 K monoclinically, N-(tri-t-butoxysilyl)aniline crystallizes orthorhombically.
    Notes: Derivate des para-substituierten N-(Tri-t-butoxysilyl)anilins (t-BuO)3SiNRC6H4X-p, R = H, CH3 mit Substituenten hoher Elektronenaffinität (X = CN, NO2) wurden nach einem neuen Eintopfverfahren aus Tri-t-butoxychlorsilan, Kalium-t-butanolat und dem entsprechend substituierten Anilin dargestellt. Für Substituenten niederer Elektronenaffinität (X = OMe, H) wird die Methode der Metallierung von Anilinen mit Natriumamid bevorzugt. Vier Kristallstrukturen wurden bestimmt. N-(Tri-t-butoxysilyl)-p-nitroanilin, N-Methyl-(N-tri-t-butoxysilyl)-p-nitroanilin und N-(Tri-t-butoxysilyl)-p-cyanoanilin kristallisieren bei 298 K monoklin, N-(Tri-t-butoxysilyl)anilin kristallisiert orthorhombisch.
