Tetradentate Schiff base ligands and their complexes: Synthesis, structural characterization, thermal, electrochemical and alkane oxidation

Three Schiff base ligands (H2L1-H2L 3) with N2O2 donor sites were synthesized by condensation of 1,5-diaminonapthalene with benzaldehyde derivatives. A series of Cu(II), Co(II), Ni(II), Mn(II) and Cr(III) complexes were prepared and characterized by spectroscopic and analytical methods. Thermal, electrochemical and alkane oxidation reactions of the ligands and their metal complexes were investigated. Extensive application of 1D (1H, 13C NMR) and 2D (COSY, HETCOR, HMBC and TOSCY) NMR techniques were used to characterize the structures of the ligands and establish the 1H and 13C resonance assignments of the three ligands. Ligands H2L1 and H2L3 were obtained as single crystals from THF solution and characterized by X-ray diffraction. Both molecules are centrosymmetric and asymmetric unit contains one half of the molecule. Catalytic alkane oxidation reactions with the transition metal complexes investigated using cyclohexane and cyclooctane as substrates. The Cu(II) and Cr(III) complexes showed good catalytic activity in the oxidation of cyclohexane and cyclooctane to desired oxidized products. Electrochemical and thermal properties of the compounds were also investigated.

Complex heterobimetallic salts derived from 1-ethoxycarbonyl-1- cyanoethylene-2,2-dithiolatodioxouranate(VI) ion: Preparation and properties

The reaction of K2[UO2(ecda)2] (generated in situ) with cationic complexes [M(N-N)3]X2 [M = Fe(II), Ru(II), Co(II), Ni(II), Cu(II), Zn(II) or Cd(II); N-N = 2,2′-dipyridyl (dipy), 1,10-phenanthroline (phen) or ethylenediamine (en); ecda2- = 1-ethoxycarbonyl-1-cyanoethylene-2,2- dithiolate; X = Cl-, NO3- or 1/2 SO42-] and n-Pr4NI in 1:1/1:2 molar ratio afforded the complex bimetallic salts [M(N-N)3][UO2(ecda)2] and the complex salt [n-Pr4N]2[UO2(ecda)2], that have been characterized on the basis of elemental analyses, molar conductance and magnetic susceptibility measurements, electrochemical and relevant spectroscopic studies. UV-visible absorption spectra in DMSO support the existence of ion-pair charge transfer (IPCT) absorption band which occurs due to charge transfer interaction between [Fe(phen)3/Ru(dipy)3]2+ and [UO2(ecda)2]2+ion. Temperature dependent (303-373 K) pressed pellet conductivities of the complexes have been studied. All the bimetallic salts of this series comprise discrete tris- chelated octahedral cations [M(N-N)3]2+ and his-chelated dioxouranium(-V1) anion, [UO2(ecda)2]2- with no sign of ligand exchange reaction in solution during the course of their formation.

Total synthesis of haminol A: An analysis of vinylpyridine metathesis reactivity

The total synthesis of haminol A has been completed featuring a masked-alkene metathesis reaction followed by bis-acyloxysulfone elimination to install the 1,3,8-triene subunit. During the course of our synthesis, the metathesis reactivity of 3-vinylpyridine was evaluated and our data suggest the rapid formation of a ruthenium pyridylalkylidene that no longer participates in productive metathesis. A chemotaxis assay using Caenorhabditis elegans demonstrated that haminol A produced an avoidance response from this organism.

Facile entry to germanate and stannate complexes [(eta6-arene)RuCl(eta2-dppm)]+[ECl3]- (E = Ge, Sn) as potent anti-cancer agents

A series of arene Ru(II) salt complexes of the type [(eta6-arene)RuCl(eta2-dppm)]+[ECl3]- (arene = C6H6, p-cymene, 1,3,5-Me3C6H3; E = Ge, Sn) bearing trichlorogermanate and trichlorostannate anions are reported. Starting from the known complexes: [(eta6-C6H6)RuCl2(eta1-dppm)] (1), [(eta6-p-cymene)RuCl2(eta1-dppm)] (3) and the novel complex [(eta6-1,3,5-Me3C6H3)RuCl2(eta1-dppm)] (7) (dppm = 1,1-bis(diphenylphosphino)methane), reactions with SnCl2 or GeCl2(dioxane) respectively afforded, by halide abstraction at the ruthenium(II) centres in 1, 3 or 7 the salts: [(eta6-C6H6)RuCl(eta2-dppm)]+ SnCl3? (2), [(eta6-p-cymene)RuCl(eta2-dppm)]+ SnCl3? (4), [(eta6-C6H6)RuCl(eta2-dppm)]+ GeCl3? (5), [(eta6-p-cymene)RuCl(eta2-dppm)]+ GeCl3? (6), [(eta6-1,3,5-Me3C6H3)RuCl(eta2-dppm)]+ SnCl3? (8) and [(eta6-1,3,5-Me3C6H3)RuCl(eta2-dppm)]+ GeCl3? (9). The trichlorostannate complexes 2, 4 and 8 are extremely rare examples of ruthenium complexes bearing the SnCl3? counter anion, and the complexes 5, 6 and 9 are the first examples of ruthenium trichlorogermanate complexes to be reported. All compounds were isolated in high yields as air stable materials and were spectroscopically characterized by multinuclear NMR: (1H, 31P{1H}, 13C{1H}), Infra-red (IR), UV?Vis, and high resolution electrospray ionization mass spectrometry (HR-ESI-MS), the latter both in (+) and (?) mode. Additionally, single crystal X-ray diffraction analyses of salts 4 and 6 are reported, revealing pseudotetrahedral Ru(II) centres with eta6 bound p-cymene ligands and eta2-bound dppm ligands with statistical disorder on the ECl3- anions (E = Ge (6), Sn (4)). Density functional theory calculations (B3LYP with the basis set 6-31 + G(d,p) for H, C, P and Cl atoms; while for Ru, Ge, and Sn atoms DGDZVP basis set) are reported for salts 4 and 6 revealing localization of the LUMOs on the ruthenium-arene rings and some localization on the chloride atom. Finally, MTT in vitro cytotoxicity assays for the MCF-7 and MDA-MB-231 breast cancer cell lines are reported for all complexes and compared to cisplatin. All complexes show remarkable in vitro cytotoxic activity and most are considerably more cytotoxic than cisplatin in both breast cancer cell lines: IC50 values range from 2.25 muM (compound 2) to 5.97 muM (compound 9) (cisplatin = 5.74 muM) in MCF-7 cells; 2.20 muM (compound 2) to 6.39 muM (compound 5) (cisplatin = 13.98 muM) in MDA-MB-231. Moreover, when compared to non-malignant breast epithelial cells (MCF12A), all complexes exhibit promising selectivity indices (SI) with compound 5 having the highest SI in MCF-7 cells at 4.8; and compound 6 at 3.65 in MDA-MB-231, with most of the other compounds also being considerably more selective than cisplatin on both cell-lines (SI = 2.26 on MCF-7 and 0.93 on MDA-MB-231). A clonogenic assay was conducted for salts 5 and 6 and the results reveal that both compounds inhibited long-term (14 days) survival in both breast cancer cell lines tested indicating these drugs are very promising candidates for pre-clinical studies.

Heteroditopic rhenium(I) and ruthenium(II) bipyridyl calix[4]arene receptors for binding cation-anion ion pairs

New heteroditopic ion pair receptors that contain rhenium(I) and ruthenium(II) bipyridyl amide anion recognition sites covalently linked to a lower rim calix[4]arene tetraester alkali metal cation binding site have been prepared and shown to bind alkali metal (Li+, Na+)-halide (Br-, I-) ion pair species. Proton NMR titration studies reveal the lower rim ester co-bound alkali metal cation significantly enhances the strength of bromide and iodide binding in acetonitrile solutions with the largest positive co-operative binding effect of sixtyfold observed with bromide and the lithium complex of one receptor. Solid/liquid extraction experiments show two of the receptors are capable of solubilising NaCl and NaOAc in dichloromethane solutions. The Royal Society of Chemistry 2001.

Novel platinum group metal complexes bearing bidentate chelating pyrimidyl-NHC and pyrimidyl imidazolyl-thione ligands: Syntheses, spectral and structural characterization

A family of novel platinum group metal complexes containing bidentate chelating 1-pyrimidyl-3-methylimidazolyl bromide (HL1¡¤Br) and 1-pyrimidyl-3-methylimidazolyl-2-thione (L2) ligands has been synthesized. The synthetic protocol for the formation of these complexes differs from one ligand to the other. Treatment of ligand (HL1¡¤Br) with the metal precursors led to the formation of complexes via in situ carbene transfer reactions. The silver-NHC complex (1) was formed by the reaction of HL1¡¤Br with silver oxide under light-free conditions. Subsequent addition of appropriate metal precursors to the silver-NHC complex yielded [(eta6-arene)Ru(L1)Cl] PF6 complexes {arene = C6H6 (2), p- iPrC6H4Me (3), C6Me6 (4)} on stirring at room temperature, whereas the complexes [CpRu(L1)(PPh 3)]PF6 {Cp = C5H5 (5), C 9H7 (6)} were obtained under reflux conditions. In the case of ligand L2, stirring of equimolar quantities of metal precursors and the ligand at room temperature yielded [(eta6-arene)Ru(L2)Cl]PF 6 {arene = C6H6 (7), p-iPrC 6H4Me (8), C6Me6 (9)}, and [Cp*M(L2)Cl]PF6 {Cp* = C5Me5, M = Rh (10), Ir (11)}. All these complexes were characterized by CHN analysis, IR, NMR and mass spectrometry besides confirmation by single crystal X-ray diffraction studies for some representative complexes as their hexafluorophosphate salts [3]PF6, [5]PF6, [8]PF 6 and [10]PF6.
