摘要

METHOD FOR PREPARING ACETOXYSILOXANES AND ORGANO(POLY)SILOXANES HAVING HALOGEN BONDED TO SILICON Organo(poly)siloxanes having halogen bonded directly to silicon, or acetoxysiloxanes are prepared by reacting organo (poly)siloxanes having hydrogen bonded directly to silicon, with an allyl compound in the presence of metallic palladium, ruthenium or rhodium, or an acetylacetone or phosphine complex, or compound containing palladium, ruthenium or rhodium in which the allyl compound is an allyl halide having 3 carbon atoms per molecule or allyl acetate.
