Electric Literature of 141-30-0, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 141-30-0, Name is 3,6-Dichloropyridazine, molecular formula is C4H2Cl2N2. In a Article，once mentioned of 141-30-0

To probe the coordination approach of pyridazine and pyrazine ligands, five new complexes of [CuII2L2Cl2] (1), [CuII(L-H)(NO3)(H2O)2](NO 3)(H2O) (2), {[CuII(L-H)(H2O)] (ClO4)2(H2O)}n (3), [Cu II2L2(OH)](NO3)(H2O) 2 (4), [CuII2L2(OH)](ClO 4) (5) based on Schiff base ligand (E)-3-chloro-6-[2-(pyrazin-2- ylmethylene)hydrazinyl]pyridazine (HL) bearing pyridazinyl and pyrazinyl groups have been synthesized and characterized by IR spectra, elemental analyses, the bond valence sum (BVS) analyses, powder X-ray diffraction (PXRD) analyses, X-ray single crystal diffraction and density function theory calculations. The structures of 1, 2 and 3 suggest that the second nitrogen donors of the pyrazinyl unit can link with other metal ions to construct a higher dimensional architecture by the reaction of HL with Cu(ClO4)2 [CuCl2 for 1, Cu(NO3)2 for 2 and Cu(ClO 4)2 for 3]. The structures of 4 and 5 indicate that additional donor units of the pyridazinyl chromophore can bind multiple metal ions to form a multi-metallic cluster, when the protons of the hydrazone backbones are abstracted in the presence of triethylamine to strengthen the coordination behavior of the second nitrogen atom. However, for 1, the protons of the hydrazone backbone are lost with or without triethylamine and the additional nitrogen atoms of the pyrazinyl and pyridazinyl groups are not found to connect to other metal ions, which can probably be assigned to the strong coupling effect of chlorine ions. Magnetic measurements display weak antiferromagnetic coupling between the copper(ii) ions in 1 and 5, and ferromagnetic coupling in 3. In addition, the antioxidant activities of HL and 1-5 were also studied.

Chemistry is traditionally divided into organic and inorganic chemistry. COA of Formula: C5H6N2O, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 13327-27-0

Ring-closing olefin metathesis (RCM) has been applied to the efficient synthesis of densely and diversely substituted pyridine and pyridazine frameworks. Routes to suitable metathesis precursors have been investigated and the scope of the metathesis step has been probed. The metathesis products function as precursors to the target heteroaromatic structures via elimination of a suitable leaving group, which also facilitates earlier steps by serving as a protecting group at nitrogen. Further functionalisation of the metathesis products is possible both prior to and after aromatisation. The net result is a powerful strategy for the de novo synthesis of highly substituted heteroaromatic scaffolds.

Electric Literature of 141-30-0, 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.141-30-0, Name is 3,6-Dichloropyridazine, molecular formula is C4H2Cl2N2. In a article，once mentioned of 141-30-0

In this study thirteen 6-substituted-3(2H)-pyridazinone-2-acetyl-2- (substituted/-nonsubstituted benzal)hydrazone V derivatives were synthesized as acetylcholinesterase and butyrylcholinesterase inhibitors. Ten of the synthesized compounds were synthesized for the first time in this study and the rest of them had been synthesized in a previous study. The structures of compounds V were elucidated by IR, 1H-NMR and MASS spectra. The acetylcholinesterase (AChE) and butyrylcholinesterase (BChe) inhibitory activities of V derivatives were measured using Ellman’s method. While some of the 6-substituted-3(2 H )-pyridazinone-2-propyl-3-(substituted/-nonsubstituted benzal)hydrazone V derivatives exhibited significant AChE inhibitory activity, none of the compounds showed BChE inhibitory activity. These results indicate that V derivatives were AChE inhibitors with AChE/ BChE selectivity. ECV ? Editio Cantor Verlag.
