C3v-Symmetrical Tribenzotriquinacenes Bearing Six Benzylic Tentacle Groups at the Molecular Periphery

The synthesis and characterization of several C3v-symmetrically extended tribenzotriquinacenes (TBTQs) bearing six benzylic C1-tentacular functional groups at the arene periphery were reported. A new C3v-symmetrical hexakis(chloromethyl)-substituted TBTQ derivative was used as the key intermediate, and other derivatives were synthesized with high efficiency by either sixfold nucleophilic substitution reactions with phenols or sixfold Friedel-Crafts alkylation reactions with various arenes.
