Abstract
Process for silylation of compounds having at least one active hydrogen atom, by reaction with compounds having the grouping (see formula), characterized in that the silylation is carried out in the presence of 0.01 to 5% by weight (referred to organosilicon compounds) of anionically active catalysts, which in a solution at a maximum of 1% decrease the surface tension of the water to a value of < 50 mn. M-1, or its derivatives not soluble in water, and the catalysts belong to one of the following groups: a) monoesters or diesters of sulfuric acid; b) onium salts, derived from nitrogen, of the monoesters of sulfuric acid; c) fluoroalkyl sulfonic acids, alkylsulfonic acids, alkylarylsulfonic acids or their onium salts derived from nitrogen; d) alkyl or trialkyl sulphonic esters of the acids mentioned in c).
