1,3-dihalo-1,1,3,3-tetra(organyl)disiloxanes of the general formula XR2Si—O—SiR2X??(1) are prepared by reacting hydrogen halide with the corresponding 1,3-dihydro-1,1,3,3-tetra(organyl)disiloxanes of the general formula HR2Si—O—SiR2H??(2), in which R is an alkyl or halogen substituted alkyl group and X is halogen, in the presence of a catalyst selected from transition metals of the 8th subgroup of the periodic table of the elements, or compounds or complexes of these transition metals.
