- CONTRIBUTIONS TO THE CHEMISTRY OF ORGANIC SILICON-NITROGEN-COMPOUNDS, I. SYNTHESIS OF N,N-BIS-(TRIMETHYLSILYL)AMINES
-
The preparation of N,N-bis-(trimethylsilyl)amines 1 has been investigated.Three convenient methods are reported: A, Transfer of (catalytically) activated Tms-groups to amines starting from N-silylated carbonamides, B, silylation of amines with trimethylsilylchloride 5/NEt3 in the presence of TiCl4, C, silylation of primary amines 4 or mono-(trimethylsilyl)amines 16 with CF3SO3 Tms/NEt3 or TmsI/NEt3.Methods A and B are limited to the silylation of (ar)alkylamines which have no branched α-position. Key words: N,N-bis-(trimethylsilyl)amines; N,N-bis-silylamines; N-silylcarbonamides.
