Summary

The reactivity of Pt(II) complexes towards organosilanes is greatly enhanced by hemilabile chelating ligands R2N-R'-PPh2 (P∩N). (P∩N)PtMe2 reacts with HSiR3 to yield the complexes (P∩N)Pt(SiR3)Me and (P∩N)Pt(SiR3)2 along with MeSiR3. An excess of HSi(OMe)3 is catalytically converted into Si(OMe)4. PnN-substituted Pt(II) complexes also catalyze the formation of disiloxanes from HSiR3 and C-Cl/Si-H exchange reactions. The latter reaction yields dechlorinated hydrocarbons and chlorosilanes. Reaction of (P∩N)PtMe2 with ClSiPhMe2 results in the stoichiometric formation of Ph2Me4Si2, along with the Pt(IV) complex (P∩N)Pt(Cl)Me3 and the Pt(II) complex ((P∩N)Pt(Cl)Me. The corresponding bisphosphine complex (dppe)PtMe2 undergoes none of these reactions.
