Fluoride's new role: Selective and efficient monoreductions of imides can be achieved with polymethylhydrosiloxane (PMHS) and tetra‐n‐butylammonium fluoride (TBAF) as catalyst (see scheme). The system is characterized by good chemoselectivity, operational simplicity, and functional‐group tolerance; a concise mechanistic proposal was possible from in situ spectroscopic investigations.
