Abstract
Process for preparing organosilicon compounds having silicon-bonded groups containing olefinic unsaturation by reaction of a silicon compound having SiH groups with a diene having at least 5 carbon atoms and in which the unsaturation is located at the terminal carbon atoms. The process is carried out in the presence of a catalyst which has been prepared by reacting (i) an inorganic solid having surface reactive groups, (ii) an organosilicom compound having a group reactive with the inorganic solid and a group containing nitrogen and/or sulphur and (iii) a platinum compound or complex PtLb in which L is a ligand. Products have reduced content of isomers resulting from migration of double bond to internal position.
