Popis: Defined crystalline amino-substituted organosilanes were prepared by reaction of N-methylaniline with 1,1,2,2-tetrachloro-1,2-dimethyldisilane. It is possible to selectively prepare mono-, di-, and triaminodisilanes depending on the reactant ratio. The X-ray structure analyses of 1,2-dichloro-1,2-dimethyl-1,2-bis(N-methylanilino)disilane (2), 1-chloro-1,2-dimethyl-1,2,2-tris(N-methylanilino)disilane (3), and 1,2-dimethyl-1,1,2,2-tetrakis(N-methylanilino)disilane (4) were performed. The absolute structure of 2 was determined by crystallographic methods. Compound 2 is a useful reagent for preparing a variety of other aminoorganodisilanes like [Me(PhMeN)2Si]2 (4), [FMe(PhMeN)Si]2 (12), [(PhCC)Me(PhMeN)Si]2 (13), [(p-MeC6H4)Me(PhMeN)Si]2 (14), and [(PhCH2)Me(PhMeN)Si]2 (15). Other chloroorganooligosilanes also react with N-methylaniline to give PhMeN[SiMe2]2Cl (5), PhMeN[SiMe2]2NMePh (6), Cl[SiMe2]3NMePh (7), PhMeN[SiMe2]3NMePh (8), Cl[SiMe2]4NMePh (9), MeClSi[Si(NMePh)ClMe]2 (10), and MeSi[Si(NMePh)ClMe]3 (11).
