A new addition reaction of zinc-alkynyl ides to N-acyl and N-phosphinoyl iminiums is reported. These can be prepared in situ from imines with acid halides in the presence of a Zn-acetylide. The reaction is general with regard to imine, alkyne, and acid halides, allowing access to a large number of differentially protected propargylic amines.
