synthesis and dna interaction studies of new cobalt (ii) complexes containing different dinitrogen aaromatic ligands with calf thymus dna using different spectroscopy methods
در این مطالعه بر هم کنش این چهار کمپلکس با dna تیموس گوساله توسط روش های اسپکتروفتومتری، فلوریمتری، دو رنگ نمائی دورانی، و ویسکوزیمتری بررسی شدند تا اثر استخلاف های متیل بر روی لیگاندهای فنانترولین بررسی گردد.
Phosphine-substituted sterically encumbered pyrrolyl ligands - synthesis and reactivity studies.
The sterically encumbered pyrrolyl KPyr(tBu2) (1-K, Pyr(tBu2) = 2,5-(Me3C)2C4H2N) reacts with PCl3, (iPr)2PCl and Ph2PCl exclusively at the C3-position to yield a series of phosphine-substituted pyrroles HPyr(tBu2R) (R = PCl2 (2-H), (iPr)2P (4-H) and Ph2P (5-H)). Pyrrole 2-H can further be functionalized with MeLi (3 equiv.) to yield LiPyr(tBu2PMe2) (3-Li). The coordination chemistry of these p...
متن کاملInfrared spectroscopy of discrete uranyl anion complexes.
The Free-Electron Laser for Infrared Experiments (FELIX) was used to study the wavelength-resolved multiple photon photodissociation of discrete, gas-phase uranyl (UO22+) complexes containing a single anionic ligand (A), with or without ligated solvent molecules (S). The uranyl antisymmetric and symmetric stretching frequencies were measured for complexes with general formula [UO2A(S)n]+, where...
متن کاملMixed sandwich thorium complexes incorporating bis(tri-isopropylsilyl)cyclooctatetraenyl and pentamethylcyclopentadienyl ligands: synthesis, structure and reactivity.
The Th(iv) mixed-sandwich halide complexes Th(COT(TIPS2))Cp*X (where COT(TIPS2) = 1,4-{Si(i)Pr(3)}(2)C(8)H(6), X = Cl, I) have been synthesised, and structurally characterised. When Th(COT(TIPS2))Cp*I is reduced in situ in the presence of CO(2), a mixture of dimeric carboxylate and oxalate complexes {Th(COT(TIPS2))Cp*}(2)(μ-κ(1):κ(2)-CO(3)) and {Th(COT(TIPS2))Cp*}(2)(μ-κ(2):κ(2)-C(2)O(4)) are f...
متن کاملSynthesis, Spectroscopy and Magnetism of Alkoxobridged Dinuclear Copper(II) Complexes with 2 Amino Picolines as the Ligands
The synthesis, spectroscopic and magnetic characterization of a series of new alkoxo-bridged binuclear copper (II) compounds are described. All complexes have the general formula [Cu (m-OR)(L)2]2(ClO4)2 · x H2O, in which m-OR = CH3O-, C2H5O- or C3H7O-<e...
