- AlCl3 as an efficient catalyst toward the synthesis of 1,6-dihydropyrazine-2,3-dicarbonitrile derivatives
-
Aluminium chloride has been shown to be an efficient catalyst for the multicomponent reactions of diaminomaleonitrile (DAMN), ketones or aldehydes, and isocyanides for the synthesis of 1,6-dihydropyrazine-2,3-dicarbonitrile derivatives using comparative s
