Synthetic Route of 1448-87-9, New Advances in Chemical Research in 2021. 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.1448-87-9, Name is 2-Chloroquinoxaline, molecular formula is C8H5ClN2. In a article，once mentioned of 1448-87-9

The rate of the reaction of 2-chloroquinoxaline with piperidine in dimethyl sulphoxide was measured over a wide range of amine concentrations and at several temperatures.It was found that the order with respect to the nucleophile is close to 1 between 300 and 320 K, but is definitely less at lower and higher temperatures.It is suggested that below 300 K an unreactive charge-transfer complex is formed between the reactants which dissociates at higher temperatures, whereas at temperatures higher than 320 K an unproductive ? complex is formed, the concentration of which increases with increase in temperature.

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 1448-87-9 is helpful to your research. Synthetic Route of 1448-87-9

A series of forty-seven quinoxaline derivatives, 2-(XYZC6H 2CHN-NH)-quinoxalines, 1, have been synthesized and evaluated for their activity against four cancer cell lines: potent cytotoxicities were found (IC50 ranging from 0.316 to 15.749 muM). The structure-activity relationship (SAR) analysis indicated that the number, the positions and the type of substituents attached to the aromatic ring are critical for biological activity. The activities do not depend on the electronic effects of the substituents nor on the lypophilicities of the molecules. A common feature of active compounds is an ortho-hydroxy group in the phenyl ring. A potential role of these ortho-hydroxy derivatives is as N,N,O-tridentate ligands complexing with a vital metal, such as iron, and thereby preventing proliferation of cells. The most active compound was (1: X,Y = 2,3-(OH)2, Z = H), which displayed a potent cytotoxicity comparable to that of the reference drug doxorubicin.

Oligoacenes are of interest as organic p-type semiconductors for use in electronic devices, but their use as n-type semiconductors is limited. N-Heteroacenes have been investigated as oligoacene-based n-type semiconductors due to their enhanced electron affinity. Herein, we report the synthesis, X-ray crystal structures, electrochemical, and field-effect transistor properties of TANC and BTANC.

One-step direct conversion of a series of heteroeyelie aldehydes to heterocyclie esters is reported here by the use of thiamine hydrochloride as a catalyst in the absence of nitrogen atmosphere in a reasonably high yield. This method exclusively produces heteroeyelie esters in most cases (specially with more electron-withdrawing heteroeyelie aldehydes) without the formation of side products like heteroin. Thus the method developed looks promising and general for the synthesis of electron-withdrawing heteroeyelie esters from the corresponding aldehydes. Copyright

Aim: Quinoxaline-1,4-dioxide derivatives are synthetic heterocyclic compounds with multiple biological and pharmacological effects. In this study, we investigated the bioactivity of five quinoxaline-1,4-di-N-oxides derivatives in different animal cell lines. Materials & methods: Using in vitro cell cultures, we evaluated the influence of quinoxaline-1,4-dioxide, 2-methylquinoxaline-1,4-dioxide, 2-amino-3-cyanoquinoxaline-1,4-dioxide, 3-methyl-2-quinoxalinecarboxamide-1,4-dioxide and 2-hydroxyphenazine-N,N-dioxide (2HF) in the viability, migration and proliferation of nonmalignant (3T3-L1 and human dermal microvascular endothelial cell) and malignant (B16-F10, MeWo, GL-261 and BC3H1) cell lines. Results: The viability IC50 concentrations for each quinoxaline-1,4-di-N-oxide derivative were calculated, and a concomitant reduction of migration and proliferation was observed mainly in malignant cell lines. Conclusion: 2HF exhibited potent anti-viability, anti-migration and anti-proliferative actions selectively in tumor cells, nevertheless more studies are required to further investigate 2HF promising biologic effects.

Quinoxaline-bridged bidentate bis-imidazolium dicarbene ligand 1,1?-(quinoxaline-2,3-diyl)bis(3-methyl-1H-imidazol-3-ium) hexafluorophosphate salt H2L·2PF6 (3) was prepared by a two-step reaction based on 2,3-bis(imidazol-1-yl)quinoxaline (1). First, the 2,3-bis(imidazol-1-yl)quinoxaline reacted with CH3I resulting in the 1,1?-(quinoxaline-2,3-diyl)bis(3-methyl-1H-imidazol-3-ium) iodide salt H2L·2I (2), then through anion exchange reactions with NH4PF6 in water produced the desired bis-imidazolium bidentate ligand H2L·2PF6 (3). Reaction of the bidentate bis-imidazolium ligands H2L·2PF6 (3) with Ag2O in acetonitrile gave the macrocyclic binuclear silver(I) carbene complex [Ag2(L)2]·2PF6·CH3CN (4). Nickel carbene complex [Ni(L)PPh3Cl]·PF6·2DMSO (5) was obtained via transmetalation of 4 with Ni(PPh3)2Cl2 in DMSO. The bidentate carbene ligand is a chelating ligand in 5, while bridging in 4. The imidazolium ligand H2L·2PF6 (3) and transition metal carbene complexes 4 and 5 have been fully characterized by elemental analysis, NMR, ESI-MS spectroscopy, and X-ray diffraction analyses. Furthermore, the UV and luminescent properties of 3?5 were also studied.
