variety of vinylcyclopropanes, bearing an ester group in the β-position, upon expose to pentacarbonyl iron at elevated temperatures is established. Dienic esters with a single configuration of the double bonds are obtained by this route in high yield. Steric and electronic factors, governing the course of the reactions, were investigated using nitrile and alkyl substituted vinylcyclopropanes.
