Abstract

Transition metal-containing organosiloxanes of at least three organosiloxane units, comprising at least one transition metal complex, chemically bonded via ligands selected from among amino, phosphino or sulfido groups of Pt, Pd, Rh, Ru, Os or Ir, excluding those organosiloxanes which contain exclusively Pt(O) complexes bonded via amino ligands, are used as homogeneous hydrosilylation catalysts.
