A Simple and Highly Efficient Iron Catalyst for a [2+2+2] Cycloaddition to Form Pyridines

Abstract

Joined by iron: The iron catalyst for the formation of pyridines at room temperature (see scheme), which was generated in situ from an inorganic iron salt and a diphosphine ligand, exhibited high reactivity and regioselectivity.
