Cadmium(II) complexes of 5-bromo-salicylaldehyde and alpha-diimines: Synthesis, structure and interaction with calf-thymus DNA and albumins

Five Cd(II) complexes, four dinuclear (1-4) and a mononuclear one (5), with the anion of 5-Br-salicylaldehyde (5-Br-salo-), were synthesized and characterized as [Cd(5-Br-salo)2(CH3OH)]2 (1), [Cd(5-Br-salo)2(bipy)]2 (2), [Cd(5-Br-salo)2(phen)]2 (3), [Cd(5-Br-salo)(neoc)(NO3)]2 (4) and [Cd(5-Br-salo)2(dpamH)] (5). The complexes were characterized by spectroscopy (IR, UV-vis, 1H NMR), elemental analysis and molar conductivity measurements. The structures for three complexes (2, 3 and 5) were determined by X-ray crystallography providing different coordination modes of the 5-Br-salicylaldehydo ligand. The complexes bind to DNA mainly by intercalation, as concluded by the viscosity measurements and the EB-displacement studies from the EB-DNA complex and present high DNA-binding constants (Kb), as calculated by the Wolfe-Shimer equation and plots. The interaction of the complexes with serum albumins was studied by fluorescence emission spectroscopy and the determined binding constants exhibit relative high values.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 499-40-1, you can also check out more blogs about499-40-1

Synthesis of phenanthrenes and polycyclic heteroarenes by transition-metal catalyzed cycloisomerization reactions

Readily available biphenyl derivatives containing an alkyne unit at one of their ortho-positions are converted into substituted phenanthrenes on exposure to catalytic amounts of either PtCl2, AuCl, AuCl3, GaCl3 or InCl3 in toluene. This 6-endo-dig cyclization likely proceeds through initial pi-complexation of the alkyne unit followed by interception of the resulting eta2-metal species by the adjacent arene ring. The reaction is inherently modular, allowing for substantial structural variations and for the incorporation of substituents at any site of the phenanthrene product. Moreover, it is readily extended to the heterocyclic series as exemplified by the preparation of benzoindoles, benzocarbazoles, naphthothiophenes, as well as bridgehead nitrogen heterocycles such as pyrrolo[1,2-a]quinolines. Depending on the chosen catalyst, biaryls bearing halo-alkyne units can either be converted into the corresponding 10-halo-phenanthrenes or into the isomeric 9-halo-phenanthrenes; in the latter case, the concomitant 1,2-halide shift is best explained by assuming a metal vinylidene species as the reactive intermediate. The scope of this novel method for the preparation of polycyclic arenes is illustrated by the total synthesis of a series of polyoxygenated phenanthrenes that are close relatives of the anticancer agent combretastatin A-4, as well as by the total synthesis of the aporphine alkaloid O-methyl-dehydroisopiline and its naturally occurring symmetrical dimer.

Molecular Structure, Acidic Properties, and Kinetic Behavior of the Cationic Complex (Methyl)(dimethyl sulfoxide)(bis-2-pyridylamine)platinum(II) Ion

The complex [PtMe(dpa) (Me2SO)]+(CF3SO3)- (dpa = bis(2-pyridyl)amine) crystallizes in the monoclinic space group P21/c with a = 11.010(2) A, b = 18.366(2) A, c = 10.333(5) A, beta= 111.62(2), and Z = 4. Least-squares refinement of the structure led to an R factor of 2.41%. To avoid steric repulsions, the chelate six-membered ring assumes a boat configuration in which the two pyridyl rings are folded with a dihedral angle of 46.4(1). There is a strong hydrogen-bonding interaction involving the amine hydrogen (N3) and a triflate anion oxygen O3, 2.898(5) A. The tendency by the NH group of the ligand moiety to attract anions is maintained in a solution of nonpolar solvents. Tight ion-pairs of structure similar to that in the solid state are formed with PF6-, BF4-, CF3SO3-, and Cl- in chloroform, as shown by the strong dependence of the chemical shifts of the NH, H(3), and H(3?) protons of the dpa ligand on the nature of the counterion. 19F{1H} HOESY experiments on [PtMe(dpa)(Me2SO)]+(PF6)- in CD2Cl2 confirmed that the preferential position of the counterion is close to the NH proton. The absorption spectra are also strongly affected by the nature of the counterion. This allowed for a stopped-flow measure of the PF6- for Cl- exchange rate at the NH site, which is a bimolecular process with k2 = 96.4 ¡À4 M-1 s-1. The cation [PtMe(dpa)(Me2SO)]+ shows acidic properties in water (pKcan be isolated on basification. Ion-pairing and full deprotonation of the amine ligand have remarkably little effect on the reactivity, as shown by the comparison of the rates of isotopic exchange of dimethyl sulfoxide of these species followed by 1H NMR in chloroform. The rates of substitution of dimethyl sulfoxide from by various charged nucleophiles were measured in methanol, where ion-pairing effects are absent, and compared with those of the parent (phen = 1,10-phenanthroline) complex. Because of the reduced capacity of electron withdrawal from the metal of the ancillary ligand, the dpa complex is less reactive and possesses a minor nucleophilic discrimination ability compared with the phen complex.

Synthesis, structures, electrochemistry and magnetic properties of a cyano-bridged {Fe2Co2} molecular square

The reaction of tricyanometallate precursor, (Bu4N)[(Tp*) Fe(CN)3] (Tp* = hydrotris(3,5-dimethylpyrazol-l-yl)borate) with Co(ClO4)2¡¤6H2O in the presence of the bidentate dpa (dpa = 2,2?-dipyridyl amine) ligand affords one novel cyano-bridged heterobimetallic {Fe2Co2} molecular square, [FeIII(Tp*)(CN)3]2[CoII(dpa) 2]2?2ClO4?4H2O? 4CH3OH (1). The molecular structure was determined by single-crystal X-ray diffraction. In compound 1, FeIII ion is coordinated by three cyanide carbon atoms and three nitrogen atoms of Tp* anions. Whereas, the CoII ion is surrounded by two cyanide nitrogen atoms and four nitrogen atoms from two bidentate dpa ligands. Cyclic voltammetry (CV) measurements showed that complex 1 exhibited one quasi-reversible waves (0.1 V vs SCE) in the reduction process, and irreversible waves in the oxidation process. Magnetic measurements indicate that complex 1 exhibits a strong intramolecular ferromagnetic interaction between the low-spin FeIII(S = 1/2) and high-spin CoII(S = 3/2) ions.

Thermodynamic equilibria between polyalcohols and cyclic ethers in high-temperature liquid water

Thermodynamic equilibrium constants between polyalcohols and cyclic ethers in water at 573 K were determined by measuring their concentrations after the long-term reaction in a batch reactor. Intramolecular dehydration reactions of polyalcohols were important for conversion of biomass-derived carbohydrates; however, the yields of products were limited by thermodynamic equilibria between polyalcohols and products. All the thermodynamic equilibrium constants were estimated by the long-term dehydration reaction of 1 mol ¡¤dm-3 polyalcohol aqueous solutions at 573 K. The thermodynamic equilibrium constants between butanepolyols or pentanepolyols and five-membered or six-membered cyclic ethers were within a range from (39 to 337) mol ¡¤dm-3.
