possessing an N-(quinolin-8-yl)amide directing group are ortho-allylated with allylphenylether in the presence of an iron/diphosphine catalyst and an organometallic base at 50-70 °C. The reaction proceeds via fast iron-catalyzed C-H activation, followed by reaction of the resulting iron intermediate with the allylether in γ-selective fashion.
