Abstract 5,7-Dimethyl-3-phenylfuroxano[5,4-a]pyrimidiniumperchlorate (II) was obtained by the reaction of 4-amino-3-phenylfuroxan with acetylacetone in the presence of HClO4. The structures of II and its furazan analog I were proved by x-ray diffraction analysis, and their 13C NMR spectra were studied. The cations of I and II (which contain a conjugated condensed system with delocalization of the positive charge) and their monocyclic analogs — phenylfarazan, 3-phenylfuroxan, and 4,6-dimethylpyrimidine — were subjected to quantum-chemical calculation by the CNDO/2 method.
