Process for the production of organo substituted silicon compounds

Organo-substituted silicon compounds are prepared by reacting an alkyl orthosilicate with an alkyl, cyclo-alkyl, aryl or aralkyl halogenide in the presence of an alkali metal. The reaction is preferably carried out in an inert organic solvent, with the alkali metal either in a finely-divided state or in the form of an amalgam. The proportions of the reactants may be varied with the resultant formation of compounds in which one, two or three of the alkoxy radicals are replaced by alkyl &c. radicals. If the reaction is carried out in the presence of excess orthosilicate which is one of the preferred forms of the invention, the main product is a compound of the structure R1Si(OR)3.
