New Advances in Chemical Research, May 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. 2213-63-0, In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2

Transition metal-catalyzed cross-coupling reactions represent one of the most powerful tools in modern organic chemistry. Due to the relevance of nitrogen heterocyclic compounds for many areas, the development of new and effective methods to afford coupled products from these reagents has become very attractive for organic synthesis. Quinoxaline derivatives encompass one of the most privileged classes of heterocycles, being part of several biologically and technologically relevant compounds. Cross-coupling reactions involving the building block 2,3-dichloroquinoxaline (DCQX) emerge as a promising approach from several synthetic approaches reported for the synthesis of quinoxaline derivatives. The present article consists of a literature review regarding the substrate DCQX as a partner for C-C and C-N cross-coupling reactions. Examples of classical Suzuki-Miyaura, Heck and Sonogashira cross-coupling reactions are presented, as well as other synthetic transformations that lead to the formation of fused polycyclic compounds through heterocyclization processes. Some mechanistic insights are also presented. Notably, most of the publications addressing the subject presented herein are from the last decade, and several of the synthesized compounds are relevant due to their applications in many fields. These features emphasize the relevance of DCQX as a substrate for cross-coupling reactions for organic synthesis.

New series of [1,2,4]triazolo [4,3-a]quinoxaline and bis([1,2,4]triazolo)[4,3-a:3?,4?-c]quinoxaline derivatives have been designed, synthesized and biologically evaluated for their cytotoxic activities against three tumor cell lines (HePG-2, Hep-2 and Caco-2). Compounds 16e, 21, 25a and 25b exhibited the highest activities against the examined cell lines with IC50 values ranging from 0.29 to 0.90 muM comparable to that of doxorubicin (IC50 ranging from 0.51 to 0.73 muM). The most active members were further evaluated for their topoisomerase II (Topo II) inhibitory activities and DNA intercalating affinities as potential mechanisms for their anti-proliferative activities. Interestingly, the results of Topo II inhibition and DNA binding assays were consistent with that of the cytotoxicity data, where the most potent anti-proliferative derivatives exhibited good Topo II inhibitory activities and DNA binding affinities, comparable to that of doxorubicin. Moreover, the most active compound 25a caused cell cycle arrest at G2/M phase and induced apoptosis in Caco-2 cells. In addition, Furthermore, molecular docking studies were performed for the novel compounds against DNA-Topo II complex to investigate their binding patterns. Based on these studies, it was concluded that DNA binding and/or Topo II inhibition may contribute to the observed cytotoxicity of the synthesized compounds.

Heating with bromotrimethylsilane converts 2-chloropyridine into 2-bromopyridine and 2-chloro-6-methylpyridine into 2-bromo-6-methylpyridine. Both 2-chloropyridines and 2-bromopyridines give the corresponding iodo compound when treated with in situ generated iodotrimethylsilane. Although 3- and 4-chloropyridine are completely inert, 2,4-dichloropyridine undergoes the halogen/halogen exchange simultaneously at the 2- and 4-position. Halogen displacement takes place exclusively at the 2-position with 2,3-dichloropyridine and 2,5-dichloropyridine. In agreement with the intermediacy of N-trimethylsilylpyridinium salts as a prerequisite for the occurrence of halogen exchange, neither 2-fluoropyridine and 2-fluoro-6-methylpyridine nor any 2,6-dihalopyridine reacts. Finally, bromine/chlorine and iodine/chlorine substitution can also be accomplished with 2-or 4-chloroquinoline, 1-chloroisoquinoline, 2-chloropyrimidine, chloropyrazine and 2,3-dichloroquinoxaline as substrates.
