EXAMPLE 1 Preparation of 7-Nitro-1,4-dithiino(2,3-b)quinoxaline-2,3-dicarbonitrile To a solution of 2,3-dichloro-6-nitroquinoxaline (1.0 g, 0.0041 mol) in dimethylformamide (20 mL) is added, in several portions, disodium-Z-1,2-dicyano-1,2-ethylenedithiolate (1.1 g, 0.0045 mol). The resulting solution is stirred overnight at room temperature. Water (100 mL) is slowly added to the reaction mixture, dropwise, with stirring. The resulting solid is isolated by filtration, washed with water and dried, giving a dark purple powder. The recovered material weighs 0.92 g and has a melting point of 222 to 225 C. A calculated overall yield of 72 percent is achieved. The structure identity is confirmed by proton nuclear magnetic resonance spectroscopy (1 H), carbon nuclear magnetic resonance spectroscopy (NMR), infrared spectroscopy (IR) and mass spectrometry (MS).
2379-60-4, 2379-60-4 2 3-Dichloro-6-nitroquinoxaline 689090, aquinoxaline compound, is more and more widely used in various fields.
