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.
直接将卤素键合到硅原子的有机(聚)硅氧烷,或者乙酰氧硅氧烷是通过在金属钯、钌或铑的存在下,或者在存在乙酰丙酮或膦配合物,或者含有钯、钌或铑的化合物的情况下,将直接键合到硅原子的有机(聚)硅氧烷与烯丙基化合物反应制备的,其中烯丙基化合物是每个分子含有3个碳原子的烯丙基卤化物或烯丙基醋酸酯。
