In a nickel-promotedcyclization, 1,3-diene can serve as a ligand and it affects the reaction course. A s-cis conformation of 1,3-diene is necessary for coordination to the metal, and the highest selectivity () was obtained in the reaction of 1b with hydride nickel complex 4 using cyclopentadiene 2 2 as a ligand.
