The reaction of a series of ertyhro-2,3-dibromo-1,3-diaryl-1-porpanones with four molar equivalents of semicarbazide hydrochloride or thiosemicarbazide in dioxane or ethanol leads to the formation of trisubstituted pyrazolines and their 4-bromo derivatives. The pyrazolines have been identified by chemical and spectral data. A reaction mechanism is also proposed.
