Arenesulfonamides 10, cyanamide 29, and sulfamide 32 react with allylic bis-carbonates 8 (Z and E) and 9 under Pd(0)-catalysis to afford medium and large unsaturated heterocycles instead of three and/or five-membered ring compounds. Stable 15-membered palladium-containing rings were also isolated from arenesulfonamides and 8, with three trans olefinic systems coordinated to the metal. NMR and MALDI-TOF
