An iron salt and a bipyridine‐type ligand catalyze the ortho‐allylation of 1‐arylpyrazoles and congeners with allyl phenyl ether under mild conditions (0 °C). The ligand, an organozinc base, and the nature of the allylating reagent are crucial for the success of this reaction. Under these conditions, a competitive phenylation reaction is largely retarded, and cross‐coupling of the organozinc with the
