Acetylene gas readily adds to the C=N bond of ketimines in KOtBu/DMSO solution at room temperature to afford terminal propargylamines with a quaternary carbon center in up to 94 % yield. The reaction represents a new Csp3–Csp bond formation under mild transition metal free conditions using available widespread starting materials covering a broad scope of ketimines.
