New piperazinones are obtained in satisfactory yields by reaction of 1,2-diaza-1,3-butadienes with 1,2-diamines under solvent-free conditions. In polar solvents, the same reagents give rise to interesting dihydropyrazines and then to pyrazines by oxidatio
Straightforward access to pyrazines, piperazinones, and quinoxalines by reactions of 1,2-diaza-1,3-butadienes with 1,2-diamines under solution, solvent-free, or solid-phase conditions
