Good old copper! A new general procedure to couple aliphatic and aromatic Grignardreagents with alkynyl halides under copper catalysis is described (see scheme; NMP=N‐methylpyrrolidinone). The reaction is chemoselective and allows preparation of a vast array of simple and functionalized internal alkynes in high yields.
