Production processes for triorganomonoalkoxysilanes and triorganomonochlorosilanes
A silane containing a bulky hydrocarbon group or groups R therein and having the formula (III) [in-line-formulae]R3-(x+y)(R1)x(R2)ySi(OR3) [/in-line-formulae] can be produced by reacting a silane of the formula (I) [in-line-formulae](R1)x(R2) ySiCl3-(x+y)(OR3) [/in-line-formulae] with a Grignard reagent of the formula (II) [in-line-formulae]RMgX [/in-line-formulae] Further, a tri-organo-chlorosilane of the formula (XIIa) [in-line-formulae](R1)(R2)(R3)SiCl [/in-line-formulae] can be produced by reacting a tri-organo-silane of the formula (XIa) [in-line-formulae](R1)(R2)(R3)SiZ1 [/in-line-formulae] with hydrochloric acid. Furthermore, a tri-organo-monoalkoxysilane of the formula (XXIII) [in-line-formulae]R3-(x+y)(R1)x(R2)ySi(OR3) [/in-line-formulae] can be produced when a silane of the formula (XXI) [in-line-formulae](R1)x(R2)ySiCl4-(x+y) [/in-line-formulae] is reacted with a Grignard reagent of the formula (XXII) [in-line-formulae]RMgX [/in-line-formulae] with addition of and reaction with an alcohol or an epoxy compound during the reaction.

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