This catalyst is commercially available, inexpensive, reusable, stable to air and moisture, and relatively non-toxic. Furthermore, very short reaction times, high yields of products, mild reaction conditions, absence of solvent, and easy work-up are other considerable advantages of these procedures. Also, a resonable mechanism has been proposed for the current reaction. The chemical structure and purity of the products were characterized by 1H NMR and IR spectroscopy.}, keywords = {Quinoxaline,2,3-dihydropyrazine,selectfluor,1,2-diamine,1,2-dicarbonyl}, url = {https://icc.journals.pnu.ac.ir/article_875.html}, eprint = {https://icc.journals.pnu.ac.ir/article_875_f641796d2487c8db80828f4b3cfce08c.pdf} }
