The heterotetra- and bimetallic uranium(iv)-rhodium(i) complexes [UIVI2(μ-OArP-1κ1O,2κ1P)2RhI(μ-I)]2 (2) (ArPO- = 2-(diphenylphosphino)-6-tert-butyl-4-methylphenoxide) and UIVI(μ-I)(μ-OArP-1κ1O,2κ1P)3RhI (3) were prepared by treatment of UIVI(OArP-κ2O,P)3 (1) with rhodium(i) iodide olefin complexes. The reaction of 1 with the monodentate cyclooctene (coe) rhodium(i) precursor [(coe)2RhII]2 give...

Iridium catalysts supported on anatase with high surface area showed excellent activities for the acceptor-less dehydrogenation synthesis of benzoxazoles from 2-aminophenol and primary alcohols. The catalytic activity greatly depended titania supports, iridium precursors, loading species. Catalysts JRC (Japan Reference Catalyst)-TIO-10 highest dehydrogenative reaction. Preparation using [Ir(cod...

In the complex cation of the binuclear solvated title salt, [Pt2F(SbF6)2(C8H12)2]SbF6 0.75HF, an F atom bridges the two platinum(II) atoms with a bond angle of 123.3 (2) . The corresponding Pt—F bond lengths are in the range of other fluorine-bridged binuclear platinum(II) complexes. Two of the three SbF6 anions each coordinate with one F atom to one platinum(II) atom. Including the -bound cycl...

The iridium catalyst [IrCl(cod)]2 -phosphine-I2 (cod=1,5-cyclooctadiene) selectively reduced isoxazolium triflates to isoxazolines or isoxazolidines in the presence of H2 . The iridium-catalyzed hydrogenation proceeded in high-to-good enantioselectivity when an optically active phosphine-oxazoline ligand was used. The 3-substituted 5-arylisoxazolium salts were transformed into 4-isoxazolines wi...

Purpose. To develop a scale to measure (social) participation for use in rehabilitation, stigma reduction and social integration programmes. Method. A scale development study was carried out in Nepal, India and Brazil using standard methods. The instrument was to be based on the Participation domains of the International Classification of Functioning, Disability and Health (ICF), be cross-cultu...

Open-cage derivative C(60)(O)(4)(OH)(2)(NC(6)H(4)(t)Bu)(2) reacts with ICl to form a Baeyer-Villiger type product, which yields an intense green product upon treatment with HI.

A series of cationic rhodium(I) and iridium(I) complexes of the type [M(L[symbol: see text]L)(C2)]BAr(F)24 (where M = Rh or Ir, L[symbol: see text]L = bis(pyrazol-1-yl)methane (bpm), bis(N-methylimidazol-2-yl)methane (bim) or 1-(2-(diphenylphosphino)ethyl)-3,5-diphenylpyrazole (Ph2PyP), C2 = 1,5-cyclooctadiene (COD) or (CO)2 and BAr(F)24 = tetrakis[3,5-bis(trifluoromethyl)phenyl]borate) were sy...

The Ir(i) complexes [Ir(cod)(κP,C,P'-NHO(PPh2))]PF6 and [IrCl(cod)(κC-NHO(OMe))] (cod = 1,5-cyclooctadiene, NHO(PPh2) = 1,3-bis(2-(diphenylphosphanyl)ethyl)-2-methyleneimidazoline) and NHO(OMe) = 1,3-bis(2-(methoxyethyl)-2-methyleneimidazoline), both featuring an N-heterocyclic olefin ligand (NHO), have been tested in the transfer hydrogenation reaction; this representing the first example of t...
