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.
含有笨重烃基团R的硅烷化合物可以通过将式(I)(R1)x(R2)ySiCl3−(x+y)(OR3)的硅烷化合物与式(II)RMgX的格氏试剂反应产生,其中R3−(x+y)(R1)x(R2)ySi(OR3)的化学式为(III)。此外,可以通过将式(XIa)(R1)(R2)(R3)SiZ1的三元有机硅烷与盐酸反应来产生式(XIIa)(R1)(R2)(R3)SiCl的三元有机氯硅烷。此外,可以在反应期间加入并反应醇或环氧化合物,从而使式(XXI)(R1)x(R2)ySiCl4−(x+y)的硅烷化合物与式(XXII)RMgX的格氏试剂反应并生成式(XXIII)R3−(x+y)(R1)x(R2)ySi(OR3)的三元有机单烷氧硅烷。
