Successive treatment of arenes with β-bromopropionyl chloride and AlCl3, followed by the reactions with hydrazines and Na2CO3, and then with MnO2 gave the corresponding 3-arylpyrazoles in one pot in good to moderate yields. The same successive treatment of arenes with β-bromopropionyl chloride and AlCl3, followed by the reactions with hydroxylamine and KF gave the corresponding 3-arylisoxazolines in one pot in good to moderate yields. © 2020 Elsevier Science.
