Article abstract of DOI:10.1002/zaac.201300646

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 ₂Si(NMePh)₂ (6b). The compounds were comprehensively characterized by ¹H, ¹³C, ²⁹Si 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. Copyright
