نویسندگان
چکیده
In this paper, we introduce Brønsted acidic ionic liquid (BAIL), (4-sulfobutyl) tris (4-sulfophenyl) phosphonium hydrogen sulfate as a green and efficient catalyst for the synthesis of 2,3-disubstituted quinoxaline derivatives via the one-pot condensation reaction of various o-phenylenediamine with 1,2-diketone derivatives. At all experiments, the desired products were synthesized successfully. The described novel synthesis method proposes several advantages of safety, mild condition, short reaction times, high yields, simplicity and easy workup compared to the traditional method of synthesis.
