Palladium-catalyzed synthesis of trans-4-(N,N-Bis(2-pyridyl)amino)stilbene. A new intrinsic fluoroionophore for transition metal ions

(formula presented) The title compound (1) has been synthesized via sequential Pd-catalyzed amination reactions and investigated as an intrinsic fluoroionophore. The efficiency in the synthesis of 1 strongly depends on the order of couplings among the substrates. Compound 1 displays fluorescence quenching upon the binding of transition metal ions, where the binding-triggered conformational twisting and in turn the inhibition of internal charge transfer (ICT) play an important role.

Excited state dynamics of symmetric and asymmetric Cr3(dpa)4Cl2 measured using femtosecond transient absorption spectroscopy

Herein, the excited-state dynamics of an extended metal atom chain complex, Cr3(dpa)4Cl2 (dpa = dipyridylamide), in tetrahydrofuran solution were investigated using femtosecond transient absorption spectroscopy. Upon excitation at a wavelength of 330 nm, two distinct excited-state absorption species with varied dynamics were identified and assigned to the symmetric (s-) and unsymmetric (u-) Cr3(dpa)4Cl2. The major species is s-Cr3(dpa)4Cl2 that undergoes rapid conversion at less than 100 fs from the ligand-centred pi-pi? state, which is the initially accessed state, to the metal-centred d-d state and then vibrational cooling accompanying the structural relaxation at a time constant ?2.2 ps. Most of the s-form is recovered to the ground state at ?200 ps. For u-Cr3(dpa)4Cl2, a similar rapid conversion to d-d states is observed, and the geometric/vibrational relaxation is ?0.8 ps. The second recovery of the ground state with approximately equal amplitude is observed at a time constant of ?5 ns. This might be because many d-d states exist and about half of them inefficiently couple with the ground state surface.

PREPARATION AND PHYSICO-CHEMICAL PROPERTIES OF THE TERNARY COMPLEXES FORMED BETWEEN ADENOSINE 5′-TRIPHOSPHORIC ACID, BIS(2-PYRIDYL)AMINE, AND DIVALENT METAL IONS. CRYSTAL AND MOLECULAR STRUCTURES OF THE COMPOUNDS CONTAINING Mg(II) AND Ca(II)

Ternary compounds formed between M , adenosine 5′-triphosphate , and bis(2-pyridyl)amine(bipyam) have been prepared The solid compounds are crystalline and have a stoicheiometry described by the formula M(Hatp)(Hbipyam)*nH2O (n = 2-9).X-ray powder diffraction patterns are similar.Potentiometric titrations in aqueous solution show the presence of two ionizable protons.Visible spectra suggest an octahedral co-ordination geometry.I.r. spectra indicated essentially the same type of metal-ligand interactions in all the complexes and show that Hatp(3-) co-ordinates to the metal through the oxygen atoms of the alpha, beta, and gamma phosphate groups.The ternary compounds where M = Mg(II)(1) or Ca(II)(2) have been studied by single-crystal X-ray diffration techniques and their molecular structures determined.The two species are isostructural and can be formulated as 22*9H2O (2).Both (1) and (2) crystallise in space group C2221 (Z = 4), with a = 22.734(3), b = 10.233(3), c = 30.997(4) Angstroem for (1) and a = 22.965(3), b = 10.154(3), c = 32.390(4) Angstroem for (2).X-ray diffraction data were collected on a Philips automatic diffractometer and the structures solved by direct methods using the SIR (Semi-invariant Representation) package and refined by full-matrix least squares to final R values of 0.111 and 0.124 (1 088 and 1 008 independent observed reflections) for (1) and (2) respectively.In the (4-) units the metal ions lie on a two-fold axis with an octahedral co-ordination geometry completed by the oxygen atoms of the alpha, beta, and gamma phosphate groups of two symmetry-related Hatp(3-) molecules.The co-ordination polyhedron of (1) is nearly regular but in (2) it is significantly distorted.The phosphate chains have a folded configuration in both (1) and (2).In both complexes there are no bonding interactions between the metal ions and the adenine base.The metal atoms of the (2+) cations are also located on two-fold axes while the six co-ordinated water molecules form hydrogen bonds with the phosphate chains.The Hbipyam(1+) molecules do not co-ordinate to the metal ions and are disordered around two-fold axes.Strong stacking interactions exist between Hbipyam(1+) and purine rings.

Synthesis, Characterization, and Stereochemistry of Bridged Intramolecularly Alkylated Cobaloximes; Monomeric and Dimeric Complexes of Different Configuration

Ligands have been synthesized containing two vicinal dioxime functions joined by a carbon chain to which is attached in the centre a bromomethyl or chloromethyl group (20, 22, 25).These ligands, upon reaction with cobalt(II) chloride in the presence of pyridine and sodium borohydride afforded bridged intramolecularly alkylated cobaloximes.When the vicinal dioxime functions are separated by a chain of nine carbon atoms mainly dimeric complexes are formed.Two of these, 26 and 27, were isolated and characterized by spectroscopic methods and their structures were established by X-ray crystallography.Ligands containing eleven or thirteen carbon atoms between the dioxime functions afforded mainly monomeric cobaloximes with cis configuration, e. g. 28.The trans-monomeric complex 30 was produced along with the cis isomer when the number of carbon atoms in the bridge was raised to fifteen.

Evaluation of fatty acids and volatile compounds in iranian ghee by head space-solid phase microextraction coupled with gas chromatography/mass spectroscopy

Ghee, a nutritional dairy product in Iranian culture, can be easily produced on a small scale. This study was undertaken to analyze fatty acids and volatile compounds of collected ghee samples from different ghee production sites of Iran (Ilam, Kermanshah and Hamedan) using HeadSpace Solid Phase MicroExtraction (HS-SPME) technique. According to the results, palmitic and oleic acids were the dominant fatty acids in all the samples investigated. Further, it might be concluded that compounds such as dodecane, acetone, butyric acid, hexanoic acid, 2-pentanone, 2-heptanone, and 2-undecanone, which are present and might have accumulated as the results of oxidative, hydrolytic, or microbial activities, contribute to the flavor of ghee. Lactones, which are produced at high temperatures, were not collected in any sample except the Hamedan sample (< 1%). Low thermal processing in the ghee production prevented the formation of off-flavor volatile compounds. The qualitative and quantitative parameters determined in this study might be useful in assessing the quality of the ghee and may help the industry to improve its commercial production.
