ORGANOSILICON AND ORGANOPHOSPHORUS COMPOUNDS WITH PSEUDOHALIDE GROUPS. VI. SYNTHESIS OF ALKOXYDIMETHYLSILYL AZIDES AND SOME OF THEIR PROPERTIES

Krolevets, A. A.,Chmykhov, V. N.,Glotov, E. N.,Gontar', A. F.,Martynov, B. I.

, p. 597 - 599 (2007/10/02)

By reaction of sodium azide with alkoxydimethylsilyl chlorides in hexamethylphosphoramide previously unknown alkoxydimethylsilyl azides were prepared and some of their properties were studied.Silyl azides reacting with zinc difluoride, acyl halides, phosphorus acid chlorides, and perfluoro-2-aza-2-butene can replace halogen by both alkoxy and azido groups (depending on the nature of the halogen-containing compound).
