Synthetic Route of 5096-73-1, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.5096-73-1, Name is 6-Chloropyridazine-3-carboxylic acid, molecular formula is C5H3ClN2O2. In a article，once mentioned of 5096-73-1

The visible-light-enhanced catalytic activation of aryl chlorides for Suzuki?Miyaura cross-coupling (SMC) reactions is highly challenging because of the strength of the C?Cl bond. In this work, palladium nanoparticles (Pd NPs) were grown on a conjugated nanoporous polycarbazole (CNP), named Pd/CNP. The hybrid material Pd/CNP could catalyze the SMC reactions of aryl chlorides with arylboronic acids in water under blue LED irradiation at room temperature with high efficiency. This protocol exhibited good functional group tolerance and the catalyst could be recycled without significant loss of its catalytic activity. CNP not only provided photogenerated electrons to enrich the electron density of the Pd NPs but also generated holes for the activation of the arylboronic acids.

Compounds 1-3 were obtained in the reaction of 3,6-dichloro-pyridazines with phenylacetonitriles in the biphasic system – DMSO/50% NaOH. The chlorine atom was replaced with cycloalkylamino (4-13) and hydrazinyl (23, 24) moiety. These last compounds were condensed with aldehydes (25-34). Pyridazynylphenylacetonitriles were converted into amides 14-18 and thioamides 19-22. In compounds 2, 3 the chlorine atom was replaced with thiophenyl (37, 38) and in compound 1 with thioethyl and thiophenyl (35, 36) functional groups. In the reactions of compounds 1, 2 with ammonium polysulfide thioamides with thiol group (39, 40) and chlorine atom (41, 42) were obtained. Compounds 1-17, 19-43 were screened for antibacterial and fungicidal activities.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 1121-79-5, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1121-79-5, Name is 3-Chloro-6-methylpyridazine, molecular formula is C5H5ClN2

A novel class of luminescent tricarbonyl rhenium(I) complexes of general formula [Re2(mu-X)2(CO)6(mu-diaz)] (X = halogen and diaz = 1,2-diazine) was prepared by reacting [ReX(CO)5] with 0.5 equiv of diazine (seven different ligands were used). The bridging coordination of the diazine in these dinuclear complexes was confirmed by single-crystal X-ray analysis. Cyclic voltammetry in acetonitrile showed for all the complexes (but the phthalazine derivative) a chemically and electrochemically reversible ligand-centered reduction, as well as a reversible metal-centered bielectronic oxidation. With respect to the prototypical luminescent [ReCl(CO)3(bpy)] complex, the oxidation is more difficult and the reduction easier (about +0.3 V), so that a similar highest occupied molecular orbital-lowest unoccupied molecular orbital gap is observed. All of the complexes exhibit photoluminescence at room temperature in solution, with broad unstructured emission from metal-to-ligand charge-transfer states, at lambda in the range 579-620 nm. Lifetimes (tau = 20-2200 ns) and quantum yields (Phi up to 0.12) dramatically change upon varying the bridging ligand X and the diazine substituents: in particular, quantum yields decrease in the series Cl, Br, and I and in the presence of substituents at the alpha positions of the pyridazine ring. A combined density functional and time-dependent density functional study of the geometry, relative stability, electronic structure, and photophysical properties of all the pyridazine derivatives was performed. The nature of the excited states involved in the electronic absorption spectra was ascertained, and trends in the energy of the highest occupied and lowest unoccupied molecular orbitals upon changing the pyridazine substituents and the bridging halogen ligands were discussed. The observed emission properties of these complexes were shown to be related to a combination of steric and electronic factors affecting their ground-state geometry and their stability.

Chemistry is traditionally divided into organic and inorganic chemistry. Formula: C6H8N2O, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 38028-67-0

A linear free energy relationship, LFER, has been used to correlate 150 values of gas-chloroform partition coefficients, as log L(chl) with a standard deviation, sd, of 0.23 log units, a correlation coefficient r2 of 0.985, and an F-statistic of 1919. The equation reveals that bulk chloroform is dipolar/polarizable, of little hydrogen-bond basicity, but as strong a hydrogen-bond acid as bulk methanol or bulk ethanol. However, the main influence on gaseous solubility in chloroform is due to solute-solvent London dispersion interactions. A slightly modified LFER has been used to correlate 302 values of water-chloroform partition coefficients, as log P(chl). The correlation equation predicts log P(chl) for a further 34 compounds not used in the equation with sd = 0.17 log units. When the LFER is applied to all 335 log P(chl) values, the resulting equation has sd = 0.25, r2 = 0.971, and F = 2218.
