  Synthesis and Reactivity of New κ²-[P,N]Pt(II) Complexes of Diisopropylphosphino-Substituted 2-Dimethylaminoindene

  摘要：

  Treatment of 1-(PPr2)-Pr-i-2-NMe2-indene (1a[H]) with either cis/trans-(SMe2)(2)PtCl2 or PtCl2 provided ((2)(K) -P,N-2-NMe2-3-(PPr2)-Pr-i-indene)PtCl2 (2) in 84% and 55% yield, respectively, while the reaction of la[H] with (eta(4)-COD)PtClMe afforded ((2)(K)-P, N-2-NMe2-3-(PPr2)-Pr-i-indene)PtClMe (3) in 91% yield. Whereas in the formation of 2 and 3 the ligand precursor la[H] undergoes a rearrangement to give a coordinated 2-NMe2-3-(PPr2)-Pr-i-indene (1b[H]) ligand, la[H] reacted cleanly with 0.5 equiv of [(mu-SMe2)PtMe2](2) to give ((2)(K) -P,N-1a[H])PtMe2 (4a) in 97% yield. The isomerization of 4a to ((2)(K) -P,N-1b[H])PtMe2 (4b) in a THF/(PrOH)-Pr-i mixture is rapid and allowed for the isolation of 4b in 99% yield. Heating of 4a in CH2Cl2 resulted in the quantitative formation of 3, while the thermolysis of 4a in toluene in the presence of SMe2 afforded 5, the apparent product of intramolecular C-H activation of an NMe group. The reactivity of 4a with a variety of other two-electron donors, as well as E-H-containing substrates (E = main group fragment), is reported. Although NMR spectroscopic evidence indicated the formation of an intermediate of the type ((2)(K)-P,N-1[H])Pt(SnPh3)(Me), as well as Ph6Sn2, in the reaction of 4a with 10 equiv of Ph3SnH, negligible conversion of Ph3SnH to Ph6Sn2 was obtained when employing 1 mol % 4a as a catalyst. Single-crystal X-ray diffraction data for 2 and 5 are reported.

  exothermicity for a reaction involving a tertiary phosphine in this Pt system. Calculations using density functional theory (DFT) on the B3LYP level were applied using the simplified model reaction [PtH2(cod)] + 2(H2N)PC2H4 → [PtH2(H2N)PC2H4}2)] + cod, and these also gave a rather low substitution enthalpy (−17 kcal/mol). A charge decomposition analysis (CDA) was performed for Pt(II) and Pt(0) complexes

  A dinuclear Pt-Si complex containing bridging eta(2)-H-SiH(IMP) (IMP = 2-isopropyl-6-methylphenyl) ligands, (Ph3P)Pt[mu-eta(2)-H-SiH(IMP)]}(2) (1) has been synthesized and characterized;by NMR and X-ray crystallography. A 3c-2e nonclassical interaction. between Pt ... H ... Si is supported by spectroscopic and crystallographic data. Complex 1 reacts with the more basic and less hindered phosphine PMe2Ph to afford a different dinuclear Pt-Si complex with loss of H-2, (PhMe2P)(2)Pt[mu-SiH(IMP)]}(2) (2). Complex 2 was characterized by multinuclear NMR spectroscopy.
