  ligands R2NR′PPh2 (P∩N). Variation of the groups R and R′ allows to influence the reactivity of the complexes. (P∩N)PtMe2 reacts with HSiR3 to yield the complexes (P∩N)Pt(SiR3)Me and (P∩N)Pt(SiR3)2 along with MeSiR3 and methane. An excess of HSi(OMe)3 is catalytically converted into Si(OMe)4. P∩N-substituted Pt(II) complexes also catalyze the formation of disiloxanes from HSiR3 and CCl/SiH exchange

• Formation of cyclo- and polystannanes by dehydrogenative stannane coupling catalyzed by platinum(II) complexes

  日期：2004.4

  Reaction of (PhMe2P)(2)PtMe2 or [(kappa(2)-P,N)-Ph2PC2H4NMe2]PtMC2 with an excess of H2SnBu2 or H2SnPh2 resulted in the catalytic formation of cyclo-, oligo- and/or polystannanes. In the reaction of (PhMe2P)(2)PMe2 with H2SnBu2, linear oligomeric species H(SnBu2),H were observed in the initial stage of the reaction, which eventually converted into cyclostannanes. Only polystannanes were observed in the reaction of [(kappa(2)-P,N)-Ph2PC2H4NMe2]PtMe2 with H2SnBu2. The reactions of H2SnPh2 were similar, but more difficult to analyze due to redistribution reactions and the formation of insoluble products. The mechanism of the reactions is clearly different to that previously observed for HSnR3 because metal complexes indicative of oxidative addition/reductive elimination reactions were only observed as minor products.

  [(kappa(2)-P,N)-Me2NCH2CH2PPh2]PtMe2 reacts with trimethoxysilane to yield the methyl trimethoxysilyl complex [(kappa(2)-P,N)-Me2NCH2CH2PPh2]Pt[Si(OMe)(3)]Me, the bis(trimethoxysilyl) complex [(kappa(2)-P,N)-Me2NCH2CH2PPh2]Pt[Si(OMe)(3)](2), methyltrimethoxysilane, tetramethoxysilane, and small amounts of pentamethoxydisiloxane and hexamethoxydisiloxane. The formation of these compounds can be explained by Si-H oxidative addition/reductive elimination, as well as Si-O activation and scrambling reactions of the silicon substituents.

  Reaction of [(kappa (2)-P,N)-Ph2PCH2CH2NMe2]PtMe2 with either ethyl chloroacetate or benzyl chloride results in complex reaction mixtures, which were investigated by a combination of NMR techniques. The reactions are initiated by oxidative addition of either the C-Cl bond or of the C-CH2Cl bond, respectively. The latter is followed by a rearrangement of the intermediate Pt(IV) complex with concomitant C-N bond cleavage of the phosphinoalkylamine ligand and formation of the ylide complexes Pt[CH2=PPh2(vinyl)](NMe2R)Me-2 (R = COOEt or Ph).
