Abstract
A silane containing a bulky hydrocarbon group or groups R therein and having the formula (III)R(R)(R)Si(OR)can be produced by reacting a silane of the formula (I)(R)(R)SiCl(OR)with a Grignard reagent of the formula (II)RMgXFurther, a tri-organo-chlorosilane of the formula (XIIa)(R)(R)(R)SiClcan be produced by reacting a tri-organo-silane of the formula (XIa)(R)(R)(R)SiZwith hydrochloric acid. Furthermore, a tri-organo-monoalkoxysilane of the formula (XXIII)R(R)(R)Si(OR)can be produced when a silane of the formula (XXI)(R)(R)SiClis reacted with a Grignard reagent of the formula (XXII)RMgXwith addition of and reaction with an alcohol or an epoxy compound during the reaction.
