Vanadium-catalysed aerobic cleavage of C-C bonds in substituted cyclohexanones to afford carboxylic acids: Two model complexes with tetrahedral geometry around vanadium(V)

Two monosilanol/disilanol derivatives were synthesised by treatment of Ph3SiOH or Ph2Si(OH)2 with [nBu4N]VO3 (3) in ethanol solution. The mononuclear anionic dioxo vanadium(v) species [{Ph3SiO}2VO2]- (4) and the dinuclear complex anion [{Ph2SiO2VO2}2]2- (5) thus obtained are unusual and novel model compounds with ?Si-O-V(O)2O linkages characterised by single-crystal X-ray diffraction. The catalytic activities of these tert-butylammonium complexes, together with those of the simple vanadium derivatives 3 and 5, of the vanadyl precursors VOSO4¡¤5H2O (1) and [VO(acac)2] (2), and also of “H6[PMo9V3O40] ¡¤aq”, were tested for aerobic C-C bond cleavage in 2-hydroxycyclohexanone and 2-methylcyclohexanone. Monomeric vanadium species show the same chemistry as the polyoxometalate but with lower yields of acids or keto acids, and so the redox and acid properties of HPA-n (n = 3, 4) are better tuned. Mechanisms for these oxidation reaction, including electron transfer from a substrate coordinated to vanadium, are proposed. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.

Synthesis, characterization and crystal structures of oxovanadium(V) complexes with benzohydrazone and 8-hydroxyquinoline

Two new oxovanadium(V) complexes, [VOL1 (HQ)] (1) and [VOL2(HQ)] (2), were prepared by the reaction of [VO(acac)2] (where acac = acetylacetonate), 8-hydroxyquinoline (HHQ) with N?-(5-fluoro-2-hydroxybenzylidene)-4-fluorobenzohydrazide (H2L1) and N?-(5-fluoro-2-hydroxybenzylidene)-4-methoxybenzohydrazide (H2 L2 ), respectively, in methanol. Crystal and molecular structures of the complexes were determined by elemental analysis, infrared and UV-visible spectra and single crystal X-ray diffraction.

The V atoms in the complexes are in octahedral coordination, with the phenolate oxygen, imino nitrogen and enolate oxygen of the benzohydrazone ligand and the hydroxy oxygen of 8-hydroxyquinoline in the equatorial plane and with the pyridine nitrogen of 8-hydroxyquinoline and one oxo group in the two axial positions. Thermal stability of the complexes was also studied.

Novel vanadium complexes with rigid carboxylate ligands: Synthesis, structure and catalytic bromine dynamics of phenol red

In this work, by selecting appropriate ligands, novel vanadium complexes [VIVO(2,6-pdc)(Phen)]¡¤3H2O (1) and [(VIVO)(C5H5N2O2)2H2O]¡¤2H2O (2) (2,6-pdc = 2,6-pyridinedicarboxylic acid, Phen = 1,10-Phenanthroline monohydrate) were synthesized by the reaction of V2(SO4)3, 2,6-pdc and Phen (for 1), VO(acac)2 and C5H6N2O2 (for 2) via solution or hydrothermal methods. Two complexes were characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TG), UV-vis spectroscopy and the single crystal X-ray diffraction. Structural analyses reveal that the vanadium atom has distorted octahedral geometry in 1 and 2 with donor sets of N3O3 and N2O4, respectively. The complexes which catalyze the oxidation of the organic substrate phenol red in the presence of H2O2 and bromide exhibited catalytic bromination activity, and the reaction system is considered as an effective model for hydrogen peroxide determination. The reaction rate constant (k) for complexes 1 and 2 can be calculated as 2.13 ¡Á 102 and 2.64 ¡Á 102 (mol/L)?2s?1, respectively.

Composition and geometry of oxovanadium(IV) and (V)-aminoethanol-Schiff base complexes and stability of their peroxo complexes in solution

Vanadium(IV) and (V) complexes (VO(sal-ae)) with Schiff bases prepared from 2-aminoethanol and salicylaldehyde and its derivatives have been synthesized and characterized in solid and in solution by EPR, IR, and UV-Vis spectroscopy. The complexes of both V(IV) and V(V) contain bridges (V-O-V) by alkoxy oxygens(oxo) in the solid state. The complexes of V(IV) in dichloromethane are binuclear,in which two alkoxy oxygens serve as bridges between the two metal atoms. They are mononuclear with one solvent ligated in the equatorial plane in each complex in dimethyl sulfoxide and methanol. The extent of the formation and the stability of organic hydroperoxide complexes of V(V) prepared from the V(IV)-Schiff base complexes increase with decreasing donor number of the solvent. The difference in electron-donating and withdrawing ability of the substituent groups affects the A? values for the V(IV)-Schiff base complexes in DMSO.

Synthesis, structure and reactivity of azosalophen complexes of palladium

The ligands 2-(arylazo)-1-N-salicylidene phenylamine, H2Lsal, (where H represents the dissociable protons upon complexation) afford stable orthopalladated complexes, [(Lsal)Pd], upon treatment with Na2[PdCl4]. The dinegative anionic (Lsal)2- ligands bind Pd(II) in a tetradentate (C, N, N, O) fashion with a distorted square planar geometry. The newly synthesized palladium complexes underwent oxygen insertion into the Pd-C bond with mCPBA (m-chloroperbenzoic acid) or TBHP (terbutylhydroperoxide)/[VO(acac)2] leading to the formation of stable azosalophen complexes of Pd(II) with the (O, N, N, O) coordination mode of the oxygenated ligand.

Structural investigation of discrete solvent protonated vanadium and other transition metal complexes of N?-[(E)-(3-ethoxy-2-hydroxyphenyl)methylidene]benzohydrazide, synthetic, spectroscopic and cytotoxicity studies

A new ligand 3-ethoxysalicylaldehyde benzoic hydrazone (H2ESB) and its copper(II), nickel(II), cobalt(II), zinc(II), and dioxidovanadium(V) complexes have been synthesized and characterized by elemental analysis, IR, UV?Vis and EPR studies. Copper(II) complex (2) contains 2,2?-bipyridine as a coligand. Aroyl hydrazone and its copper and vanadium complexes were characterised by single crystal XRD. The vanadium compound crystallized in triclinic space group P1- and copper compound in orthorhombic space group P212121. The solvent molecule DMF protonates to form ammonium ion in vanadium complex which neutralises the charge on the vanadium ion. Both complexes copper and vanadium show distorted square pyramidal geometry. From EPR results, spin Hamiltonian and bonding parameters were calculated. The g values in copper complexes indicate the presence of the unpaired electron in the dx2?y2 orbital. In vitro cytotoxicity studies of aroylhydrazone and its complexes showed that copper, cobalt and vanadium complexes are more cytotoxic than hydrazone and other complexes against Dalton’s lymphoma ascites cells (DLA).

Oxidovanadium(V) Complexes Anchored on Carbon Materials as Catalysts for the Oxidation of 1-Phenylethanol

Six oxidovanadium(V) aroylhydrazone complexes derived from (3,5-di-tert-butyl-2-hydroxybenzylidene)-2-hydroxybenzohydrazide (H2L1) and (3,5-di-tert-butyl-2-hydroxybenzylidene)-2-aminobenzohydrazide (H2L2), namely, [VOL1(OEt)][VOL1(OEt) (EtOH)] (1), [VOL2(OEt)] (2), [Et3NH][VO2L1] (3), [VO2(HL2)]?2 EtOH (4), [(VOL1)2(mu-O)] (5), and [(VOL2)2(mu-O)] (6), were synthesized and characterized by elemental analysis, IR, 1H NMR, and 51V NMR spectroscopies, ESI-MS and, for 1?5, single-crystal XRD. The compounds have VO3+ (1 and 2), VO2 + (3 and 4), and V2O3 4+ (5 and 6) cores. They are active homogeneous catalysts in the microwave-assisted, solvent-free peroxidative oxidation of 1-phenylethanol to acetophenone by tBuOOH. The immobilization of the oxidovanadium complexes (1, 2, 4, and 5) on oxidized carbon materials improved the oxidation efficiency and allowed catalyst reuse with the preservation of activity.
