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. More information can be found in the Research Article by B. A. Trofimov and co-workers (DOI: 10.1002/ejoc.202501162).
Volkov et al. (Mon,) studied this question.
