We explore in detail the iron-catalyzed benzylicfluorination of substrates containing aromatic rings and electron-withdrawing groups positioned β to one another, thus providing direct access to β-fluorinated adducts. This operationally convenient process can be thought of not only as a contribution to the timely problem of benzylicfluorination but also as a functional equivalent to a conjugate addition
