L. Capella et al., SILYLCUPRATION OF N-PHENYL-N-ETHYNYL-ANILINE - A VERSATILE ROUTE TO FUNCTIONALIZED N,N-BIS(PHENYL)ENAMINES, Tetrahedron letters, 34(20), 1993, pp. 3311-3314
The silylcupration of N-phenyl-N-ethynyl-aniline, occurs regioselectiv
ely leading to silylation at the beta-carbon atom. Subsequent reaction
of the resulting vinyl copper adduct with electrophiles, opens a new
flexible route to functionalized enamines.
