• Reduced Mono-, Di-, and Tetracubane-Type Clusters Containing the [MoFe₃S₄]²⁺ Core Stabilized by Tertiary Phosphine Ligation

  vs SCE in dichloromethane. Compared to the clusters with monoanionic ligands at the iron sites, phosphine ligation shifts redox potentials to more positive values. This effect arises from reduction of cluster negative charge and the tendency of phosphines to stabilize lower oxidation states. The synthesis of reduced clusters 4 from 1 and of [Fe4S4(PPri3)4]+ from [Fe4S4Cl4]2- is accompanied by the formation

• Facile Deep and Ultradeep Hydrodesulfurization by the [(^<i>i</i>Pr₃P)Ni]₅H₆ Cluster Compared to Mononuclear Ni Sources
  作者：Manar M. Shoshani、Samuel A. Johnson

  DOI：10.1021/acs.inorgchem.5b02383

  日期：2015.12.21

  The pentanuclear nickel cluster [((Pr3P)-Pr-i)Ni](5)H-6 facilitates the room-temperature hydrodesulfurization of dibenzothiophene, 4-methyldibenzothiophene, and 4,6-dimethydibenzothiophene. These reactions provide the new tetranuclear nickel hydride sulfide [((Pr3P)-Pr-i)Ni](4)(mu-H)(4)(mu(4)-S) (1). In comparison, the dinuclear dinitrogen nickel complex [((Pr3P)-Pr-i)(2)Ni](2)(mu-N-2) undergoes oxidative addition of the CS bonds of dibenzothiophene and 4-methyl dibenzothiophene to provide the metallacycles Ni-3((PPr3)-Pr-i)(3)C12H8S (2) and Ni-3((PPr3)-Pr-i)(3)C13H10S (3), respectively, but 4,6-dimethydibenzothiophene is unreactive, even with heating to 70 degrees C for a week. The reaction of [((Pr3P)-Pr-i)Ni](5)H-6 with (SPPr3)-Pr-i in toluene provided [((Pr3P)-Pr-i)Ni](5)H-6(S) (4), which was observed and characterized by NMR spectroscopy. The addition of vinyltrimethylsilane to 4 provided the best synthetic route to 1, with ((Pr3P)-Pr-i)Ni(eta(2)-CH2=CHSiMe3)(2) (5) generated as a byproduct.
• EIGHT-ARM POLYETHYLENE GLYCOL DERIVATIVE, PRODUCTION METHOD THEREFOR, AND MODIFIEDBIO-RELATEDSUBSTANCETHEREOF

  Disclosed are an eight-arm polyethylene glycol (PEG) derivative (formula I), production method therefor and modified bio-related substance thereby. Wherein, one tetravalent group U together with four trivalent groups E c form a highly symmetrical octavalent group CORE 0 ; L c connects the octavalent group to eight PEG chains having polydispersity or monodispersity and having n 1 to n 8 as the degree of polymerization thereof; the terminal of one PEG chain is connected to at least one functional group F (k≥1); said PEG chain and F therebetween can be directly connected (g=0) or be indirectly connected via a linking group L 0 to a terminal end-branching group G (g=1); the latter provides more reactive sites for binding more drug molecules and increases the drug loading. The eight-arm polyethylene glycol derivative has a centrosymmetric or approximately centrosymmetric structure, and leads to more precise control of the molecular weight in large-scale production and much narrower distribution of molecular weight for products. The modified bio-related substance thereby has a more uniform and controllable performance.
