Anti-Markovnikov additions to N-allylic derivatives involving ammonium–carbenium superelectrophiles
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.
The superacid-promoted electrophilic Csp3–H bond activation of aliphaticamines generates superelectrophilic species that can be subsequently fluorinated. Demonstrated by low-temperature in situ NMR experiments, the ammonium–carbenium dications, crucial for this reaction, can also react with C–H bonds opening future synthesis perspectives for this mode of activation.
