In an article，Which mentioned a new discovery about 117408-98-7

Palladium-catalyzed conjugate addition of arylboronic acids to beta,beta-disubstituted enones in aqueous media is reported. Additions of a wide range of arylboronic acids to beta,beta-disubstituted enones occur to form ketone products bearing benzylic all-carbon quaternary centers. These reactions are promoted by a simple catalyst prepared from palladium trifluoracetate and 2,2?-bipyridine. The use of aqueous sodium trifluoracetate as the reaction medium significantly enhances reactivity and enables the formation of challenging bis-benzylic and ortho-substituted benzylic all-carbon quaternary centers.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 15862-18-7, name is 5,5′-Dibromo-2,2′-bipyridine, introducing its new discovery. Quality Control of: 5,5′-Dibromo-2,2′-bipyridine

Six complexes (1-6) with the type of [Ru(bpy)2L]X2 (1-3: L = L1-L3, X = Cl-; 4-6: L = L1-L3, X = PF6 -) were synthesized based on 2,2?-bipyridine and three 2,2?-bipyridine derivatives L1, L2 and L3 (L1 = 5,5?-dibromo-2, 2?-bipyridine, L2 = 5-bromo-5?-carbazolyl-2,2?-bipyridine, L3 = 5,5?-dicarbazolyl-2,2?-bipyridine). The complexes 1-6 were characterized by 1H NMR, MS(ESI) and IR spectra, along with the X-ray crystal structure analysis for 1, 5 and 6. Their photophysical properties and electrochemiluminescence (ECL) properties were investigated in detail. In the UV-Vis absorption spectra, all complexes 1-6 show strong intraligand (pi ? pi) transitions and metal-ligand charge transfer (MLCT, dpi (Ru) ? pi) bands. Upon the excitation wavelengths at ?508 nm, all complexes 1-6 exhibit typical MLCT emission of ruthenium(II) polypyridyl complexes. The introduction of carbazole moieties improves the MLCT absorption and emission intensity. The ruthenium(II) complexes 1-6 exhibit good electrochemiluminescence (ECL) properties in [Ru(bpy)2L] 2+/tri-n-propylamine (TPrA) acetonitrile solution and the complexes with PF6- showed higher ECL emission intensity than that of the complexes with Cl- based on the same ligands.

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 15862-18-7 is helpful to your research. Quality Control of: 5,5′-Dibromo-2,2′-bipyridine

A copper(II)-catalyzed intermolecular three-component oxyarylation of allenes using arylboronic acids as a carbon source and TEMPO as an oxygen source is described. The reaction proceeded under mild conditions with high regio- and stereoselectivity and functional group tolerance. A plausible reaction mechanism is proposed, involving carbocupration of allenes, homolysis of the intervening allylcopper(II), and a radical TEMPO trap.

An efficient multicomponent dipolar cycloaddition for the synthesis of polycyclic fused pyrrolizidines was developed using N-aromatic zwitterions, aldehydes, and amino acids. The developed reactions proceed through azomethine ylides generated in situ from the decarboxylated reactions of aldehydes and amino acids followed by the [3 + 2] cycloaddition of N-aromatic zwitterions under mild reaction conditions.

The reaction of c/s-[FeIII(cyclam)CI2]CI with 1 equiv of sodium N-diethyldithiocarbamate, toluene-3,4-dithiolate, and maleonitriledithiolate in methanol in the presence of triethylamine afforded the cations [FeIII(cyclam)(Et2dtc)]2+ (1), [FeIII(cyclam)(tdt)]+ (2), and [FeIII(cydam) (mnt)]+ (3), which were isolated as triflate, hexafluorophosphate, and tetrafluoroborate salt, respectively, using sodium triflate, potassium hexafluorophosphate, or sodium tetrafluoroborate as the source for the counteranion. Complexes 1, 2, and 3 possess an S = 1/2 ground state (low-spin ferric d5). These salts were characterized by X-ray crystallography, UV-vis, Moessbauer, and electron paramagnetic resonance spectroscopies. Cyclic voltammetry revealed that 2 and 3 are reversibly one-electron-reduced, generating neutral 2red and 3red, respectively, and one-electron-oxidized, generating dicationic 2ox and 3ox, respectively. Fe and S K-edge X-ray absorption spectroscopy (XAS) revealed that 2 (S = 1/2) and 2ox (S = 0) possess a low-spin ferric ion. Complexes 2 and 3 are S,S-coordinated to a closed-shell dithiolate(2-) ligand, whereas 2ox and 3ox consist of a lowspin ferric ion antiferromagnetically coupled to a dithiolate(1-) pi radical ligand. They are singlet diradicals [FeIII(cyclam)(dithiolate·)] 2+. The analysis of the sulfur K pre-edge transitions reveals significant multiplet effects in the spectra of 2 and 2ox, which provide rare experimental evidence for a singlet diradical description for 2ox. Moessbauer spectroscopy on frozen solutions of 2 red clearly show the presence of a high-spin ferrous ion (S = 2). The experimentally established electronic structures of the three members of the electron transfer series [Fe(cyclam) (dithiolate)]2+,+,0 have been verified by broken symmetry density functional theoretical calculations, which have been calibrated against the experiment by calculating XAS and Moessbauer spectra.
