Pd(PPh3)4 catalytically assembles sulfenamide, alkyne, carbon monoxide, and diphenyl diselenide regio- and stereoselectively in a one-pot four-componentcoupling reaction to yield (Z)-β-selenyl acrylamides. The reaction proceeds in good to excellent yields (60−95%) and is tolerant of a range of functional groups on both the nitrogen of the sulfenamide and the alkyne. Moderate selectivities ranging
