چکیده    A friendly benign, green, rapid and facile strategy for synthesis a series of arylquinoxalines was achieved by condensation of aromatic 1,2-diamines with arylglyoxals under claycatalyzed as an inexpensive and ecofriendly catalyst using grindstone chemistry. significant decreases in reaction times and high yields have been observed by this green chemistry approach in comparison with previously reported using toxic solvents and reflux conditions. the improved method described herein is economical, environmentally friendly, easilyoperated due to solventfree and easy workup conditions.a friendly benign, green, rapid and facile strategy for synthesis a series of arylquinoxalines was achieved by condensation of aromatic 1,2diamines with arylglyoxals under claycatalyzed as an inexpensive and ecofriendly catalyst using grindstone chemistry. significant decreases in reaction times and high yields have been observed by this green chemistry approach in comparison with previously reported using toxic solvents and reflux conditions. the improved method described herein is economical, environmentally friendly, easilyoperated due to solventfree and easy workup conditions.
