3‐diynes is described. Key for the success of this novel transformation is the utilization of an advanced palladium catalyst system with the specific ligand Neolephos. The synthetic value of this general approach to synthetically useful α‐alkynyl‐α, β‐unsaturated amides is showcased by diversification of several structurally complex molecules and marketed drugs. Control experiments and density‐functional
stereoselective synthesis of conjugated dienes was realized for the first time via Pd‐catalyzed alkoxycarbonylation of easily available 1,3‐diynes. Key to success is the utilization of the specific ligand 1,1′‐ferrocenediyl‐bis(tert‐butyl(pyridin‐2‐yl)phosphine) (L1), which allows this novel transformation to proceed at room temperature. A range of 1,2,3,4‐tetrasubstituted conjugated dienes are obtained in
