Processes for the production of tri-organo-monoalkoxysilanes and process for the production of tri-organo-monochlorosilanes |
摘要 |
A silane containing a bulky hydrocarbon group or groups R therein and having the formula (III) R3−(x+y)(R1)x(R2)ySi(OR3) can be produced by reacting a silane of the formula (I) (R1)x(R2)ySiCl3−(x+y)(OR3) with a Grignard reagent of the formula (II) RMgX Further, a tri-organo-chlorosilane of the formula (XIIa) (R1)(R2)(R3)SiCl can be produced by reacting a tri-organo-silane of the formula (XIa) (R1)(R2)(R3)SiZ1 with hydrochloric acid. Furthermore, a tri-organo-monoalkoxysilane of the formula (XXIII) R3−(x+y)(R1)x(R2)ySi(OR3) can be produced when a silane of the formula (XXI) (R1)x(R2)ySiCl4−(x+y) is reacted with a Grignard reagent of the formula (XXII) RMgX with addition of and reaction with an alcohol or an epoxy compound during the reaction.
