Unexpected linkage: The use of dicationic RuIV complexes in the Friedel–Crafts-type allylation of aromatic alcohols leads unexpectedly to the formation of a new C[BOND]C 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.
