Unexpected linkage : The use of dicationic Ru IV complexes in the Friedel–Crafts‐type allylation of aromatic alcohols leads unexpectedly to the formation of a new CC bond and not to the phenolation product (see scheme). NMR spectroscopy, diffusion data, DFT calculations, and X‐ray diffraction analysis provide new insights with respect to the mechanism of this reaction.
