Functionalization of Alkenes with Difluoromethyl Nitrile Oxide to Access the Difluoromethylated Derivatives

Electron-rich, electron-deficient, and non-activated alkenes can be rapidly functionalized by in situ-generated difluoromethyl nitrile oxide. The (3+2) cycloaddition proceeds at room temperature, has broad functional group tolerance, and can be used for ...
