been reported in the literature. Conventionally, quinoxalinederivatives were synthesized by using different catalysts such as acetic acid, molecular iodine, o-iodoxybenzoic acid, montmorillonite K-10, polyaniline sulfate, nitrilotris(methylenephosphonic acid), aqueous HF, sulfamic acid, NH4Cl-CH3OH, 26 Amberlyst-15 and metal catalysts such as cerium(IV) ammonium nitrate (CAN), gallium(III) triflate
