the synthesis of mono and 2,3-disubstitutedquinoxalines by using a AlCl3 induced (hetero)arylation of 2,3-dichloroquinoxaline. Both symmetrical and unsymmetrical 2,3-disubstitutedquinoxalines can be prepared conveniently by using this method under appropriate reaction conditions. The reaction proceeds via C–C bond formation and can be utilized for the preparation of a variety of quinoxaline derivatives
