Abstract

The reaction of 4-aryl-1,2-diaminoimidazoles with 1-aryl-2,3-dibromo-3-(4-nitrophenyl)propanones, 2-bromo-1-phenyl-3-(4-chlorophenyl)propenone, and 1,3-diarylpropynones yields 2-amino-4,5,7-triarylimidazo[1,5-b]pyridazines. The structure of one of these products was determined by x-ray diffraction analysis.
