摘要：

In a nickel-promoted cyclization, 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 (5-T/5-I=98/2) was obtained in the reaction of 1b with hydride nickel complex 4 using cyclopentadiene 22 as a ligand.
