Migita–Stille coupling of (<i>Z</i>)-β-iodoacrylates with (<i>E</i>)-α-stannyl allylic alcohols to furnish 5-alkylidene-4-substituted-5,6-dihydro-2<i>H</i>-pyran-2-ones is efficiently catalyzed by 2% Pd black in DMF, while Pd(PPh<sub>3</sub>)<sub>4</sub> is inactive. Heterogeneous Pd released in solution is most likely responsible for the catalysis. The reaction is applicable to other substrates, without having to resort to ligands, additives, and/or solid support for Pd. The resulting pyranones can be rearranged to fully functionalized pyranones in another single step
