| Abstract: | Compounds of the composition RR′SiFNR″Si(CH3)3 (R = H, F, CH3, C2H5, C3H7, C2H3, C6H5, C(CH3)3; R = F, CH3, C6H5; R″ = CH3, C(CH3)3, Si(CH3)3) are obtained by the reaction of silicontetrafluoride or organo-substituted silicon-fluorides with the lithium salts of alkylsilylamines in a molar ratio of . The disubstituted compounds RSiF(NR′Si(CH3)3)2 (R = H, F, CH3, C2H3, C6H5; R′ = CH3, C(CH3)3) result when the reactants are in a molar-ratio. Likewise the unsymmetrical siliconfluorsilylamines of the formulae F2Si(NRSi(CH3)3) (NR′Si(CH3)3) (R = CH3, R′ = C(CH3)3), as well as the trisubstituted compounds FSi(NCH3Si(CH3)3)3 and FSi(NCH3Si(CH3)3)2(N(Si(CH3)3)2) were made. By reacting phenyltrifluorsilane with dialkylamines () C6H5SiF2NR2(R = CH3, C2H5) was obtained. The IR-, mass-, 1H and 19F NMR spectra of the above-mentioned compounds are reported. |
