خلاصه مقاله:
Selectfluor [1-(chloromethyl)-4-flouro-1,4-diazoniabicyclo[2,2,2]octane bis(tetraflouroborate)] has catalyzed the preparation of quinoxaline and 2,3-dihydopyrazine derivatives through one-potcondensation of 1,2-diamines with 1,2-dicarbonyls in solvent and under solvent-free conditions. Short reaction times, high yields of products and the use of a commercially available, stable andreusable catalyst are noteworthy advantages of these methods.

کلمات کلیدی:
