Abstract: 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… read more here.

Abstract: Highlights What are the main findings? Fluorinated telechelic bis(cyclocarbonate) was synthesized through carbonylation of a fluorinated diepoxide. Fluorinated polyhydroxyurethanes (FPHUs) with different molar masses were synthesized through polyaddition reaction. Analysis showed that the FPHUs have… read more here.
