    Notes: Abstract The reaction of fluorosilanes with lithium salts of bulky amines like tetramethyl-piperidine and di-tert. butylamine leads to stable aminofluorosilanes of the type R-SiF2-NR′R″ [R=F, C(CH3)3, C6H5, C6H4N(CH3)2]. Lithium salts of silylamines react analogously: R2Si(NR′-SiF2R″)2 (R=R′= =CH3, R″=C6H5). An eight membered Si−N-ring is obtained in the reaction of a disubstituted silylaminofluorosilane with the dilithium salt of a silylamine. The mass-,1H-, and19F-NMR spectra of the above mentioned compounds are reported.

    Notes: Abstract Aminofluorosilanes react with lithiated amines undergoing LiF-elimination and substitution (1). The acyclic silicon-nitrogen-compound2 is isolated in the reaction with a difluorosilane after renewed lithiation.2 is cyclisated in the reaction with butyllithium by butane- and LiF-elimination (3). Aminofluorosilanes with bulky (4) or mesomeric stabilized (5) ligands form stable lithioaminofluorosilanes, which react with fluorosilanes giving substitution products (6, 7).6 and7 react with the lithium salt oftert-butylamin in a molar ratio of 1∶2 to give8 and9 by intramolecular cyclisation.—The mass,1H and19F nmr spectra of the compounds are reported.

    Notes: Abstract The reaction of aminofluorsilanes of the type (R=H,F) (Me 3Si)2N−SiF2R with two moles of ammonia, or of a mono- or dialkylamine, yields the corresponding amino-compounds, e.g. (Me 3Si)2N−Si(F)R−NH2, (Me 3Si)2N−Si(F)R−NHR′ and (Me 3Si)2N−Si(F)R−NR2′ (R′=Me, Et). Analogous products are obtained by reaction of the aminofluorosilanes with lithium salts of amines with bulky organic substituents in a 1 : 1 molar ratio. Alkoxy- and aryloxyaminofluorosilanes are prepared by the reaction of sodium alcoholates and sodium phenolate with (Me 3Si)2N−Si(F2)R (R=H, C2H3, C2H5, C6H5). The i.r.-, mass-,1H- and19F-NMR spectra of the above compounds are reported.

    Description / Table of Contents: Reactions of Lithio-hexamethylcyclotrisilazane with Silicon-Fluoro Compounds1-Mono- and 1,3-dilithio-2,2,4,4,6,6-hexamethylcyclotrisilazane (2, 9) react with silicon tetrafluoride or difluorodiorganylsilanes RR′SiF2 (R = F, H, CH3, C6H5 R′ = CH3, C6H5) under LiF-elimination to give the cyclotrisilazanes 3-8, 10, and 11. The di- and trisubstituted compounds 12-14 are obtained by the reaction of 2 with CH3HSiF2 and CH3SiF3 in a molar ratio of 1:1. Ring coupling by a silicon bridge is achieved by the reaction of SiF-substituted cyclotrisilazanes with lithium tert-butylamide (15), or by the reaction of these compounds with two moles of a lithiocyclotrisilazane (16). The mass, 1H-, and 19F n.m.r. spectra of the compounds are reported.

Die di- und trisubstituierten Verbindungen 12-14 sind in der Reaktion von 2 mit CH3HSiF2 sowie CH3SiF3 im Molverhältnis 1:1 erhältlich. Ringverknüpfungen über eine Siliciumbrücke gelingen durch Umsetzung der SiF-substituierten Cyclotrisilazane mit Lithium-tert-butylamid (15) sowie durch Umsetzung dieser Verbindungen mit einem weiteren mol eines lithiierten Cyclotrisilazanes (16). Die Massen-, 1H- und 19F-NMR-Spektren dieser Verbindungen werden mitgeteilt.
