cis-2,3-diaminomaleonitrile (cis-DAMN, 1), which may be converted photochemically into an imidazole intermediate (4amino-1H-imidazole-5-carbonitrile, AICN, 2). Although this reaction has been investigated in detail since its discovery by Ferris and Orgel in 1966, the mechanism of the photochemical steps remains unresolved. Herein, we address this issue from a theoretical perspective: by the use...
An efficient synthesis of (1H-tetrazole-5-yl) pyrazines is achieved by one pot multi- component coupling reaction of α-dicarbonyl compounds, 2,3-diaminomaleonitrile and sodium azide using MgFe2O4 nanoparticles as a robust catalyst under ultrasonic irradiation. This novel synthesic method using MgFe2O4 nanoparticles is easier, faster than that of using other nanoparicles. MgFe2O4 nanoparticles h...
