ChemistryEurope, Volume 4, Issue 4, April 2026.A set of selective and divergent procedures for the silylmetallation of ynamides is reported. Upon simple reaction with a silyl‐Grignard reagent in the presence of catalytic amounts of copper bromide, a β‐selective, syn‐silylmagnesiation occurs affording a unique and selective access to polysubstituted silylated enamides.
