On the move: A highly practical olefin isomerization protocol under iron catalysis has been developed. The standard conditions involve reaction of the olefin at room temperature in THF with a simple pre‐catalyst system. Allylbenzenes give propenylbenzenes; 1‐alkenes can be selectively converted to 2‐alkenes; isolated dienes give conjugated dienes; ( Z )‐olefins give ( E )‐olefins. The synthesis of propenyl‐benzenes has also been realized by an iron‐catalyzed allylation‐isomerization domino reaction in good yields.
