Synthesis and Crystal Structure of Tetrakis(pentafluorophenylamino)silaneColourless single-crystals of Tetrakis(pentafluorophenylamino) silane were obtained from the reaction of SiCl4 with monolithiated pentafluoroaniline at low temperatures. The aminosilane has been characterized by various spectroscopic methods and its crystal structure has been determined by x-ray diffraction (for details see “Inhaltsübersicht”). Thermal condensation has not been achieved. However, reaction of silicon(IV)-chloride with pentafluoroaniline in the presence of triethylamine yielded the respective tricyclosilazane.
Notes:
Tetrakis(pentafluorphenylamino)silan wurde erstmals (Umsetzung von Siliciumtetrachlorid mit monolithiiertem Pentafluoranilin) synthetisiert und durch verschiedene spektroskopische Techniken sowie Röntgenstrukturanalyse charakterisiert (I41/a; a = 19,6383(9), c = 6,5551(7) Å; 1842 Diffraktometerdaten; R = 0,054). Versuche zur thermischen Kondensation blieben ohne Erfolg, jedoch führte die Reaktion von Silicium (IV)-chlorid mit Pentafluoranilin in Gegenwart von Triethylamin als Hilfsbase zu dem entsprechenden Tricyclosilazan.
