describe a new, iron-catalyzed method for cyclopropanation of a sterically and electronically diverse range of unactivated alkenes. The strategy enables synthesis of novel classes of cyclopropanes bearing alkyl, benzyl, allyl, halide, and heteroatom substituents, as well as spirocyclic and fused bicycles. By harnessing non-stabilized alkylcarbenes, novel substituted cyclopropanes can now be accessed to facilitate
