  已知格氏试剂在镍催化剂存在下的反应性在二苯并噻吩砜（DBTO 2），4-甲基二苯并噻吩（4-MeDBTO 2）和4,6-二甲基二苯并噻吩（4,6-Me 2 DBTO 2），通过交叉偶联反应产生无硫联苯。但是，该过程涉及的机械细节仍然未知。在该报告中，与[（dippe）Ni（μ-H）] 2相比，[（dippe）Pt（μ-H）] 2与DBTO 2的反应活性降低，但第一个允许分离和分离。的几个反应中间体，例如[（dippe）的Pt全面表征（κ 2- Ç，小号-DBTO 2）]。已证明这是上述芳族砜（DBTsO 2）的所有脱氧脱硫反应中的关键中间体。

  Novel (R₂PC₂H₄PR₂)M⁰−COT Complexes (M = Pd, Pt) Having Semiaromatic η²-COT or Dianionic η²(1,4)-COT Ligands

  摘要：

  The complexes (R2PC2H4PR2)Pd(C2H4) (R = Pr-i, Bu-t) react with COT by displacement of the ethene ligand to afford the novel mononuclear complexes (R2PC2H4PR2)Pd(eta(2)-C8H8) (R = Pr-i (1a), tBu (1b)). The COT ligand of 1a,b is semiaromatic; i.e., it is planar with alternating C-C and C=C bonds as expected for the monoanion [C8H8](-). Treatment of 1a,b with (R2PC2H4PR2)Pd-alkene complexes generates the dinuclear derivatives {(R2PC2H4PR2)Pd}(2)(mu-eta(2),eta(2)-C8H8) (R = Pr-i (2a), Bu-t(2b)). The complexes 2a,b are labile; elimination of the COT ligand from 2a gives rise to homoleptic Pd-2(mu-d(i)ppe)(2). Reaction of (d(i)ppe)PtCl2 with (tmeda)(2)Li2COT or displacement of the alkene ligands in {(d(i)ppe)Pt}a(mu-eta(2),eta(2)-C8H12) (4) or (d(i)ppe)Pt(C2H4) (5) by COT produces (d(i)ppe)Pt(eta(2)-C8H8) (6a), which in the solid state also has a semiaromatic COT ligand. In solution, complex 6a is in equilibrium with the novel isomeric form (d(i)ppe)Pt-II{eta(2)(1,4)-C8H8} (6b). The complexes are characterized by IR, MS, and solution and solid-state NMR.

• Catalytic Hydrogenolysis of Biphenylene with Platinum, Palladium, and Nickel Phosphine Complexes

  bis(diisopropylphosphino)ethane) was also capable of catalyzing the hydrogenolysis of biphenylene under an atmosphere of H2 at 120 °C. The rate of hydrogenolysis increases as the concentration of biphenylene, H2, and (dippe)PtH2 increases. These observations are consistent with the C−C bond activation of biphenylene occurring via (dippe)PtH2, not [(dippe)Pt0]. The rate of catalytic hydrogenolysis was not affected

  Abstract Two unusual lithium coordinated binuclear platinum- and rhodium-hydride complexes [M(dippe)(H)]2·LiHBEt3 were synthesized and characterized by NMR spectroscopy and X-ray crystallography. Not only does the lithium ion interact with the metal hydrides, but also with the B–H bond of the borohydride.

  The synthesis and characterization of new bis-aquo platinum(II) complexes of the type [Pt(H2O)(P-P)][OTf](2) (OTf = triflate anion), in which the diphosphine P-P is a series of 1,n-bis-diphenyphosphinoalkanes (1a-d, with n = 1-4), 1,2-bis-(di-n-fluorophenylphosphino) ethanes (2a-c, with n = 2, 4-5) and 1,2-bis-dialkylphosphinoethanes (3a-e), where the alkyl substituents at phosphorus have been systematically changed (dmpe) (3a), (depe) (3b), (dippe) (3c), (dcype) (3d) are reported. These complexes were used as catalysts in the Baeyer-Villiger oxidation of 2-methylcyclohexanone, 2-methylcyclopentanone and cyclobutanone with 35% hydrogen peroxide as an environmentally friendly oxidant. The reactions were performed at 25 degrees C in a chlorinated solvent/H2O two-phase system. All the investigated catalysts performed better than the corresponding dimeric complexes of general formula [Pt(mu-OH)(P-P)](2)[BF4](2) as a consequence of the positive effect imparted by the triflate counter-anion on catalysts speciation.
