Front Cover: Pd‐Catalyzed Oxidative Cross‐Coupling of Terminal Alkynes With Secondary Phosphine Selenides in the Et ₃ N/CCl ₄ System: One‐Pot Synthesis of Alkynylphosphine Selenides (Eur. J. Org. Chem. 12/2026)

The Front Cover depicts two research fields represented by terminal alkynes and secondary phosphine selenide chemistry that have been merged with the help of the original catalyst-reagent composition, Pd(OAc)2/CCl4/Et3N, to a branched tree with exotic alkynylphosphine selenide fruits, thereby opening a window to a novel frontier research combining acetylene and chalcogen-phosphorus chemistry.
