phosphorus ylide moiety was introduced to increase the electron density of the doublebond, was developed to activate electron‐deficient alkenes for reaction with electrophilic iron carbenes. In tandem with the Wittig reaction, the reactions of α,β‐unsaturated esters with in situ generated Fecarbene complexes delivered formal CH insertion products through cyclopropanation/ring‐opening reactions.
