The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 1448-87-9, Name is 2-Chloroquinoxaline, molecular formula is C8H5ClN2. In a article，once mentioned of 1448-87-9

Cyclic voltammetry and controlled-potential electrolysis have been employed to examine the electrochemical behavior of some mono- and dichlorinated pyrazines, quinoxalines, and pyridazines at carbon and mercury cathodes in either acetonitrile or dimethylformamide containing a tetraalkylammonium salt. Unsubstituted pyrazine and pyridazine each exhibit a single reduction wave, whereas unsubstituted quinoxaline shows three cathodic waves. For the chlorinated compounds, an additional wave is seen for the reduction of each carbon-chlorine bond. Depending on the potential of the cathode, bulk electrolyses of dichlorinated pyrazines or quinoxalines afford either the monochlorinated or fully dechlorinated product, whereas the monochlorinated analogues undergo reduction to the dechlorinated species. Electrolyses of chlorinated pyridazines give dark colored solutions, but the products (apparently polymeric) cannot be detected or identified by means of conventional GC, GC-MS, and HPLC techniques.

In an article，Which mentioned a new discovery about 1448-87-9

Described in this work is a catalyst-free, in most cases neat, preparation of heterocyclic thienyl sulfides. This method utilizes 2-thiophenethiol and various activated halogenated heterocycles in a substitution-type reaction to form an interesting array of sulfides. Yields obtained are comparable to other published methods, and the reaction requires milder conditions, has shorter reaction times, and most times eliminates the need for column chromatography during workup.

Quality Control of 2-Chloro-7-nitroquinoxaline, New Advances in Chemical Research in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 55686-94-7, Name is 2-Chloro-7-nitroquinoxaline, molecular formula is C8H4ClN3O2. In a article，once mentioned of 55686-94-7

2-{4-[(7-Chloro-2-quinoxalinyl)oxy]phenoxy}propionic acid (XK469) is among the most highly and broadly active antitumor agents to have been evaluated in our laboratories and is currently scheduled to enter clinical trials in 2001. The mechanism or mechanisms of action of XK469 remain to be elaborated. Accordingly, an effort was initiated to establish a pharmacophore hypothesis to delineate the requirements of the active site, via a comprehensive program of synthesis of analogues of XK469 and evaluation of the effects of structural modification(s) on solid tumor activity. The strategy formulated chose to dissect the two-dimensional parent structure into three regions – I, ring A of quinoxaline; II, the hydroquinone connector linkage; and III, the lactic acid moiety – to determine the resultant in vitro and in vivo effects of chemical alterations in each region. Neither the A-ring unsubstituted nor the B-ring 3-chloro-regioisomer of XK469 showed antitumor activity. The modulating antitumor effect(s) of substituents of differing electronegativities, located at the several sites comprising the A-ring of region I, were next ascertained. Thus, a halogen substituent, located at the 7-position of a 2-{4-[(2-quinoxalinyl)oxy]phenoxy}propionic acid, generated the most highly and broadly active antitumor agents. A methyl, methoxy, or an azido substituent at this site generated a much less active structure, whereas 5-, 6-, 8-chloro-, 6-, 7-nitro, and 7-amino derivatives all proved to be essentially inactive. When the connector linkage (region II) of 1 was changed from that of a hydroquinone to either a resorcinol or a catechol derivative, all antitumor activity was lost. Of the carboxylic acid derivatives of XK469 (region III), i.e., CONH2, CONHCH3, CON(CH3)2, CONHOH, CONHNH2, CN, or CN4H (tetrazole), only the monomethyl- and N,N-dimethylamides proved to be active.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of 2-Chloro-7-nitroquinoxaline, you can also check out more blogs about55686-94-7
