Substitution Processes in Simple and Complicated Metal Complexes
The mechanisms of substitution in transition metal complexes are reviewed with particular emphasis on recent developments. Strong support is available for a dissociative mechanism in formation reactions, in which the release of water from the metal ion controls the rate of entry of ligand. This generalization breaks down in the case of certain protonated ligands as well as multidentate ligands ...
متن کاملA simple, general route to 2-pyridylidene transition metal complexes.
Pyridinium 2-carboxylates decompose thermally in the presence of a variety of late transition metal precursors to yield the corresponding 2-pyridylidene-like complexes. The mild reaction conditions and structural diversity that can be generated in the heterocyclic ring make this method an attractive alternative for the synthesis of 2-pyridylidene complexes. IR spectra of the Ir(i) carbonyl comp...
متن کاملA simple access to transition metal cyclopropenylidene complexes.
We report the first example of BAC-Cu complex (BAC = bis(diisopropylamino)cyclopropenylidene) and its use as a carbene-transfer reagent, allowing access to Au-, Pd-, Ir- and Rh-BAC compounds. Catalytic experiments show the high activity of the [CuCl(BAC)] complex in Click chemistry.
متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
متن کاملMetal (II) Complexes of Fluconazole: Thermal, XRD and Cytotoxicity Studies
We report thermal, X-ray diffraction (XRD) and cytotoxicity studies of complexes of fluconazole (FCZ) with Cu (II), Fe(II), Cd(II), Co(II), Ni(II), and Mn(II). From XRD measurements, FCZ and its metal complexes were identified as polycrystalline. Marked differences in the X-ray patterns of drug and its metal complexes revealed that the complexes are indeed different compounds and not just the m...
