New tetradentate N,N,N,N-chelating α-diimine ligands and their corresponding zinc and nickel complexes: synthesis, characterisation and testing as olefin polymerisation catalysts.
A series of zinc complexes of the general formula {[ZnCl(ArN=C(An)-C(An)=NAr)](+)}(2)[Zn(2)Cl(6)](2-) (where Ar = 2-(1-benzyl-1H-1,2,3-triazol-4-yl)phenyl 2a, 2-(1-(1-phenylethyl)-1H-1,2,3-triazol-4-yl)phenyl 2b, 2-(1-phenyl-1H-1,2,3-triazol-4-yl)phenyl 2c; An = acenaphthene backbone) were prepared by the condensation of acenaphthenequinone with the corresponding o-triazolyl-substituted aniline...
متن کامل(α-Diimine)tricarbonylhalorhenium complexes: the oxidation side.
The electrochemical behaviour of the complexes [Re(CO)(3)X(α-diimine)], X = Cl or Br, α-diimine = 1,4-di-tert-butyl-1,4-diaza-1,3-diene, was reinvestigated using cyclic voltammetry accompanied by IR and UV-vis spectroelectrochemistry. While the reduction results in the loss of halide, as necessary for the electrocatalytic activity of related diimine compounds, a reversible oxidation could be ob...
متن کاملHomo- and Hetero-bimetallic Flexibly Linked Dinuclear Salphen Complexes
A modification of the previously developed synthetic approach towards dinuclear flexibly linked salphen complexes is successfully utilized for the preparation of heterodinuclear salphen dimers. A dinuclear salphen species with Pd(II) and Cr(III) centers bears a stronger structural resemblance to the related bis-Cr(III) compound than the corresponding mononuclear Cr(III) salphen complex. Therefo...
متن کاملBimetallic reductive elimination from dinuclear Pd(III) complexes.
In 2009, we reported C-halogen reductive elimination reactions from dinuclear Pd(III) complexes and implicated dinuclear intermediates in Pd(OAc)(2)-catalyzed C-H oxidation chemistry. Herein, we report results of a thorough experimental and theoretical investigation of the mechanism of reductive elimination from such dinuclear Pd(III) complexes, which establish the role of each metal during red...
متن کاملDimensionality Variation in Dinuclear Cu(II) Complexes of a Heterotritopic Pyrazolate Ligand
Two new Cu(II) complexes of the ligand 3-carboxy-5-(2-pyridyl)-1H-pyrazole, H2L1, have been prepared and structurally characterized and found to be comprised of a similar [M2L2] dimer motif. Subtle variation in the synthetic conditions allowed isolation of two metal complexes: [Cu2L12(MeOH)2], 1, a discrete dimer linked by hydrogen bonding interactions in the solid state, and poly-[Cu2L12], 2, ...
