Homogeneous hydrosilylation catalysts

Transition metal-contg. organosiloxanes (I) are derived from at least 3 organosiloxane units contg. complex(es) of Pt, Pd, Rh, Ru, Os or Ir linked via amino, phosphino or sulphido gp-contg. ligands (excepting Pt(O) complexes with amino ligands only). Also claimed is a hydrosilylation process, compri...

Beschreibung
Zusammenfassung:	Transition metal-contg. organosiloxanes (I) are derived from at least 3 organosiloxane units contg. complex(es) of Pt, Pd, Rh, Ru, Os or Ir linked via amino, phosphino or sulphido gp-contg. ligands (excepting Pt(O) complexes with amino ligands only). Also claimed is a hydrosilylation process, comprising the reaction of (A) cpds. contg. residues with aliphatic C-C multiple bonds with (B) silanes or siloxanes with Si-H gps. or the reaction of (C) cpds. contg. both multiple C-C bonds and Si-H gps. with (D) cpds. (I) as catalyst. Also claimed are organopolysiloxane compsns. contg. (A) and (B), or (C), and (D). Also claimed is a process for the prodn. of (I), by reacting complexes of the above metals and weak ligands (below amino, phosphino and sulphido in the spectrochemical series) with organosiloxanes contg. amino, phosphino or sulphido gps.
