Iridium-Catalyzed Oxidant-Free Dehydrogenative CH Bond Functionalization: Selective Preparation of N-Arylpiperidines through Tandem Hydrogen Transfers
Relay to the finish: The atom‐economical tandem hydrogen autotransfer catalyzed by iridium(III) has been efficiently applied for the preparation of N‐arylpiperidines starting from easily accessible anilines, diols, and aldehydes (see scheme). This protocol is also compatible with the use of diethyl carbonate as an ecofriendly solvent.
