N-bis(trimethylsilyl)amines, which can be used for the introduction of aminoethyl groups into organic or organosilicon compounds, are prepared in good yields from N-trimethylsilylaziridine and trimethylhalosilanes. This reaction is spontaneous with trimethylbromo- and -iodosilane, whereas it is necessary to run the reactions with trimethylchlorosilane in the presence of dipolar aprotic solvents and at

symmetry and has a pyramidal arrangement around the nitrogen atom with a slightly elongated Si–N bond [1.770(4) Å], relative to those in other Si–N species having a planar nitrogen co-ordination. The results for the principal distances (ra) and angles from the combined GED/abinitiostudy of Me3SiNC2H4 are (uncertainties: one sigma): r(Si–N) = 1.770(4), r(Si–Cin-plane) = 1.868(4), r(Si–Cout-of-plane) = 1
