Nasielski-Hinkens, R.; Vande Vyver, E.; Nasielski, J. published the artcile< Regioselectivity in the reaction of nitroquinoxaline N-oxides with phosphoryl chloride>, COA of Formula: C8H4ClN3O2, the main research area is nitroquinoxaline oxide phosphoryl chloride regiochem; chloroquinoxaline; quinoxaline chloro; Meisenheimer nitroquinoxaline oxide regiochem.
Oxidation of nitroquinoxalines I (n = 0; R, R1 = H, Me) by m-ClC6H4CO2OH gave their N-oxides; the NO2 group orients the O atom preferentially to N-1, but the N-4:N-1 selectivity is diminished in the methylated derivatives Meisenheimer reaction of I (n = 1, R = R1 = H) with POCl3 gave I (n = 0, R = Cl, R1 = H). The orientation of the entering Cl is discussed on the basis of electronic effects induced by the N-oxide and NO2 groups.
Bulletin des Societes Chimiques Belges published new progress about Regiochemistry. 6272-25-9 belongs to class quinoxaline, and the molecular formula is C8H4ClN3O2, COA of Formula: C8H4ClN3O2.
