A platinum organosiloxane complex is prepared by a process including combining A) a platinous halide; B) a ketone; C) an enone additive distinct from any other starting materials or rearrangement products thereof; and D) a polyorganosiloxane having, per molecule, 2 to 4 silicon bonded terminally unsaturated hydrocarbon groups having from 2 to 6 carbon. The platinum organosiloxane complex prepared by the process is useful as a hydrosilylation catalyst.
