Katalysatoren für Hydrosilylierungsreaktionen

Novel catalysts of the general formula MXaYb, where M is Pt, Pd, Rh, Ru, Os or Ir, X is a triazene, tetrazene, tetrazdiene or pentazdiene ligand, Y is a ligand according to Claim 1, a is 1, 2, 3 or 4, and b is 0 or an integer from 1 to 6, are described. The catalysts promote the addition of Si-bonde...

Beschreibung
Zusammenfassung:	Novel catalysts of the general formula MXaYb, where M is Pt, Pd, Rh, Ru, Os or Ir, X is a triazene, tetrazene, tetrazdiene or pentazdiene ligand, Y is a ligand according to Claim 1, a is 1, 2, 3 or 4, and b is 0 or an integer from 1 to 6, are described. The catalysts promote the addition of Si-bonded hydrogen to an aliphatic multiple bond, the catalysts being activated by heating at temperatures of from 50 to 250@C, by irradiation with light, by the addition of Brönsted acids and/or by the addition of acid-forming agents. The catalysts are used in addition-crosslinking organopolysiloxane compositions and for the reaction of organosilicon compounds having Si-bonded hydrogen atoms with organic compounds having aliphatic multiple bonds.
