A palladium-catalyzed oxidativecross-coupling reaction of conjugated enynones with organoboronicacids is developed. This reaction provides an efficient methodology for the synthesis of functionalized furan derivatives, including 2-alkenylfurans and furan-substituted 1,3-dienes. Palladium–carbene migratory insertion is proposed as the key step in these transformations. Notably, the β-hydride elimination
