Tailoring the physical properties of molecular crystals though the construction of solid solutions requires the existence of isostructural crystals. Simple substitutions of a given molecular framework can give a range of different crystal structures. A se

2,3-Diaryl quinoxaline derivatives have been efficiently synthesized by cascade, metal-free, and solvent-free reaction of aryl aldehydes with aryl 1,2-diamines initiated by N-heterocyclic carbene. Compared with reported methods, this procedure has the advantages of easy work-up, reduced energy consumption, and elimination of solvent waste, hazards, and toxicity. A group of potentially bioactive compounds has been prepared for biomedical screening.
The synthesis of quinoxalines by condensation reaction of acyleins with o-phenylenediamine without solvent under microwave irradiation

A convenient synthetic method for 2,3-disubstituted quinoxalines is described. Heating the aryl or alkyl acyloins and o-phenylenediamine in a microwave oven for 3-6 minutes affords 2,3-disubstituted quinoxalines in 20-94% yields.
