A number of aminosilanes derived from N ‐methylaniline and chloroorganylsilanes were prepared and characterized. X‐ray structure analysis was performed on the crystalline derivatives Ph(Cl)Si(NMePh) 2 ( 4a ), HSi(NMePh) 3 ( 2b ), MeSi(NMePh) 3 ( 3b ), and Ph 2 Si(NMePh) 2 ( 6b ). The compounds were comprehensively characterized by 1 H, 13 C, 29 Si NMR, and IR spectroscopy. Volatile derivatives were further characterized by GC/MS. It was shown using quantum chemical methods that the planarization of the nitrogen atoms in the amino derivatives is caused by phenyl groups and silyl substituents.
