Fluorinated and Non-Fluorinated 1,4-Diarylpyrazoles via MnO<sub>2</sub>-Mediated Mechanochemical Deacylative Oxidation of 5-Acylpyrazolines

Fluorinated and Non-Fluorinated 1,4-Diarylpyrazoles via MnO<sub>2</sub>-Mediated Mechanochemical Deacylative Oxidation of 5-Acylpyrazolines

A solvent-free two-step synthesis of polyfunctionalized pyrazoles under ball-milling mechanochemical conditions was developed. The protocol comprises (3 + 2)-cycloaddition of in situ generated nitrile imines and chalcones, followed by oxidation of the initially formed 5-acylpyrazolines with activate...
