Silylcupration of N-phenyl-N-ethynyl-aniline: a versatile route to functionalized N,N-bis-(phenyl)enamines

The silylcupration of N-phenyl-N-ethynyl-aniline, occurs regioselectively leading to silylation at the ?-carbon atom. Subsequent reaction of the resulting vinyl copper adduct with electrophiles, opens a new flexible route to functionalized enamines.
