A Highly Regioselective Salt‐Free Iron‐Catalyzed Allylic Alkylation

Abstract

Ironing out the kinks: A highly regioselective allylic alkylation can be performed in the presence of catalytic amounts of an iron(−II) complex and triphenylphosphane (see scheme; EWG=electron-withdrawing group). Allyl carbonates and pronucleophiles are coupled in high yields with a high regioselectivity comparable only with that obtained with Rh catalysts. The reaction is broadly applicable and does not require external base.
