Metal‐catalyzed chain‐walking reactions have recently emerged as a powerful strategy to functionalize remote positions in organic molecules. However, a chain‐walking protocol for nonconjugated dienes remains scarcely reported, and developments are currently ongoing. In this Communication, a nickel‐catalyzed asymmetric hydrocyanation of nonconjugated dienes involving a chain‐walking process is demonstrated

Evidence is presented indicating that the PhLi-initiated cycloisomerization of olefinic primary alkyl iodides involves a radical-mediated atom transfer process that had previously been implicated in the isomerization of secondary and tertiary substrates.
