"Reaction of hydrogenosilanes with dimethyl Pt(II) complexes promoted by hemilabile P,N-chelating ligands";
Journal of Organometallic Chemistry, 686 (2003), 183 - 191.

Reaction of [(κ²-P,N)-Me₂N(CH₂)₃PPh₂]PtMe₂ [(Pr_N)PtMe₂] with HSiR₃ (triethylsilane or diphenylmethylsilane) results in the formation of MeSiR₃ and the methyl silyl complexes (P_N)Pt(Me)SiR₃. In the early stages of the reaction, the hydrido complex (P_N)Pt(Me)H is additionally observed. In the reaction of HSiMePh₂, the rearranged complex (P_N)Pt(Ph)SiMe₂Ph is also formed. The reactivity of the complexes (P_N)PtMe₂ is influenced by the kind of chelating P_N ligand and appears to depend on how easily the amino group is de-coordinated.
