The synthesis and characterization of five [Cu(P^P)(N^N)][PF6] complexes in which P^P = 2,7-bis(tert-butyl)-4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (tBu2xantphos) or the chiral 4,5-bis(mesitylphenylphosphino)-9,9-dimethylxanthene (xantphosMes2) and N^N = 2,2?-bipyridine (bpy), 6-methyl-2,2?-bipyridine (6-Mebpy) or 6,6?-dimethyl-2,2?-bipyridine (6,6?-Me2bpy) are reported. Single crystal structures of four of the compounds confirm that the copper(i) centre is in a distorted tetrahedral environment. In [Cu(xantphosMes2)(6-Mebpy)][PF6], the 6-Mebpy unit is disordered over two equally populated orientations and this disorder parallels a combination of two dynamic processes which we propose for [Cu(xantphosMes2)(N^N)]+ cations in solution. Density functional theory (DFT) calculations reveal that the energy difference between the two conformers observed in the solid-state structure of [Cu(xantphosMes2)(6-Mebpy)][PF6] differ in energy by only 0.28 kcal mol?1. Upon excitation into the MLCT region (lambdaexc = 365 nm), the [Cu(P^P)(N^N)][PF6] compounds are yellow to orange emitters. Increasing the number of Me groups in the bpy unit shifts the emission to higher energies, and moves the Cu+/Cu2+ oxidation to higher potentials. Photoluminescence quantum yields (PLQYs) of the compounds are low in solution, but in the solid state PLQYs of up to 59% (for [Cu(tBu2xantphos)(6,6?-Me2bpy)]+) are observed. Increased excited-state lifetimes at low temperature are consistent with the complexes exhibiting thermally activated delayed fluorescence (TADF). This is supported by the small energy difference calculated between the lowest-energy singlet and triplet excited states (0.17-0.25 eV). The compounds were tested in simple bilayer light-emitting electrochemical cells (LECs). The optoelectronic performances of complexes containing xantphosMes2 were generally lower with respect to those with tBu2xantphos, which led to bright and efficient devices. The best performing LECs were obtained for the complex [Cu(tBu2xantphos)(6,6?-Me2bpy)][PF6] due to the increased steric hindrance at the N^N ligand, resulting in higher PLQY.

Iron(II), cobalt(II) and nickel(II) 2+ type complexes of the tridentate termine ligands 2,2′-bipyridine-6-carbaldehyde phenylhydrazone (bph) and 2,2′-bipyridine-6-carbaldehyde 2-pyridylhydrazone (bpyh) have been prepared.The electronic spectrum of the 2+ species indicates that the field strength of these ligands is near that the iron(II) singlet/quintet crossover.Magnetic and Moessbauer spectral data reveal that salts of 2+ are essentially low spin, while those of 2+ are high spin.Salts of 2+ have strongly temperature-dependent magnetic moments which indicate a thermally induced doublet<*>quartet spin transition in the metal atom.The structure of 2 reveals meridional coordination of the tridenate units, the azomethine nitrogen of the hydrazone moiety being bound to the metal atom.There is significant twisting (8<*>3deg) of the two pyridyl rings in each ligand molecule about the interring bridge.The 2+ fragment is tetragonally compressed and the mean Ni-N distance is 2<*>0.9 Angstroem. 2 is monoclinic, space group C2/c, Z = 4, a 23<*>949(3), b 7<*>868(1), c 21<*>303(3) Angstroem, beta 117<*>95(2)deg.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 56100-22-2, molcular formula is C11H10N2, introducing its new discovery. category: catalyst-ligand

We described a novel approach for the C-H functionalization of 2,2?-bipyridine derivatives with alkynes. DFT calculations and experimental data showed a significant substituent effect at the 6-position of 2,2?-bipyridine, which weakened the adjacent N-Rh bond and provided the possibility of subsequent rollover cyclometalation, C-H activation, and functionalization.

Palladium(II)-catalyzed decarboxylative heck arylations of acyclic electron-rich olefins with internal selectivity

Despite the recent emergence of decarboxylative C-C bond forming reactions, methodologies providing internally arylated electron-rich olefins are still lacking. We herein report on palladium(II)-catalyzed decarboxylative Heck arylations of linear electron-rich olefins with excellent selectivity for the internal position. The method allows a variety of electron-rich linear olefins to undergo arylation with ortho-functionalized aromatic carboxylic acids, including heterocycles. The reaction mechanism has been explored with ESI-MS studies to confirm previous findings, and to reveal the formation of a highly stable palladium complex as a result of the Heck product reacting with the catalyst.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 56100-22-2 is helpful to your research. HPLC of Formula: C11H10N2

Mononuclear mercury(II) complexes containing bipyridine derivatives and thiocyanate ligands: Synthesis, characterization, crystal structure determination, and luminescent properties

A series of mercury(II) complexes, [Hg(N[sbnd]N)(SCN)2] (N[sbnd]N is 4,4?-dimethyl-2,2?-bipyridine in 1, 5,5?-dimethyl-2,2?-bipyridine in 2, 6,6?-dimethyl-2,2?-bipyridine in 3 and 6-methyl-2,2?-bipyridine in 4), were prepared from the reactions of Hg(SCN)2 with mentioned ligands in methanol. Suitable crystals of these complexes were obtained for X-ray diffraction measurement by methanol diffusion into a DMSO solution. The four complexes were thoroughly characterized by spectral methods (IR, UV?Vis, 13C{1H}NMR, 1H NMR and luminescence), elemental analysis (CHNS) and single crystal X-ray diffraction. The X-ray structural analysis indicated that in the structures of these complexes, the mercury(II) cation is four-coordinated in a distorted tetrahedral configuration by two S atoms from two thiocyanate anions and two N atoms from one chelating 2,2?-bipyridine derivative ligand. Also, in these complexes intermolecular interactions, for example C[sbnd]H?N hydrogen bonds (in 1?4), C[sbnd]H?S hydrogen bonds (in 1, 2 and 4), pi ? pi interactions (in 2?4), Hg?N interactions (in 2) and S?S interactions (in 4), are effective in the stabilization of the crystal structures and the formation of the 3D supramolecular complexes. Furthermore, the luminescence spectra of the title complexes show that the intensity of their emission bands are stronger than the emission bands for the free bipyridine derivative ligands.

Functionalized 2,2?-bipyridines and 2,2?:6?,2?-terpyridines via stille-type cross-coupling procedures

Stille-type cross-coupling procedures are utilized in order to prepare a variety of functionalized 2,2?-bipyridines and 2,2?:6?,2?-terpyridines. Such N-heterocyclic compounds are of great interest as chelating ligands for transitionmetal ions in the field of supramolecular chemistry. Various mono- and disubstitued 2,2?-bipyridines were synthesized in high yields and multigram scales using a modular design principle. The terpyridines may be functionalized in one step with different substituents at the outer pyridine rings and at the 4?-position of the centered ring, leading to multifunctionalized compounds. The initially obtained methyl ester and ethyl ester groups can be simply converted into bromomethyl and hydroxymethyl groups which allow further functionalization reactions.
