Bromination of quinoxaline and derivatives: Effective synthesis of some new brominated quinoxalines
Tetrahedron, 2017 Abstract The synthesis of brominated quinoxaline derivatives starting from several kinds of quinoxaline by different bromination strategies was studied. First the synthesis of some brominated quinoxalines was accomplished along with the development of an alternative and effective synthesis of some known compounds.

2-(3-Nitrophenoxy)quinoxaline [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 In the title mol-ecule, C(14)H(9)N(3)O(3), the dihedral angle between the quinoxaline and benzene rings is 77.13 (9)°. The mol-ecule is twisted about the ether-benzene O-C bond, with a C-O-C-C torsion angle of -102.8 (2)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming layers in the ab plane, with one nitro O atom accepting two ...
