Anti-Markovnikov additions to non-conjugated unsaturated amines in superacid are reported. In situ NMR studies, DFT calculations and labelled substrates reactions support the involvement of new ammoniumâcarbenium superelectrophiles in this original process.
Selective Anti-Markovnikov Cyclization and Hydrofluorination Reaction in Superacid HF/SbF<sub>5</sub>: A Tool in the Design of Nitrogen-Containing (Fluorinated) Polycyclic Systems
The selective synthesis of tetrahydroquinolines and fluorinated arylamines was performed in superacid HF/SbF5 through a superelectrophilic ammonium-carbenium activation process. This anti-Markovnikov oriented reaction was applied to the straightforward synthesis of highly valued (fluorinated) nitrogen-containing heterocyclic compounds.
