4,5-二氯邻苯二胺 | 4,5-Dichloro-1,2-phenylenediamine | 5348-42-5 | C6H6Cl2N2 | 177.033 |
A two-step sequence was developed for synthesising different disubstituted 6,7-dichloro-1,2,3,4-tetrahydroquinoxalines without blocking the reactive centres. N-dichloroacetyl-6,7-dichloro-1,2,3,4-tetrahydroquinoxaline was prepared from 6,7-dichloro-1,2,3,4-tetrahydroquinoxaline and dichloroacetyl chloride giving N-acyl-N′-dichloroacetyl-6,7-dichloro-1,2,3,4-tetrahydroquinoxalines. The structures of all the compounds were characterised by IR,1H NMR,13C NMR, and elemental analysis. The structure was determined by X-ray crystallography.
