High-Yielding and Divergent Paradigm for the Synthesis of <i>D</i><sub>2<i>h</i></sub>‑Symmetric Octakis-Substituted Pentiptycenequinones VadehraGeeta S. JiangXing DotsonJordan J. ChuGong M. Garcia-GaribayMiguel A. 2017 With a rigid fused polyaromatic framework and a well-defined, highly symmetric molecular geometry, pentiptycenes are appealing building blocks for a variety of materials applications. Unfortunately, their use has been limited by the lengthy syntheses of their functionalized derivatives. This communication describes a highly efficient, brief, divergent paradigm for the preparation of octakis-substituted pentiptycene derivatives that starts with the preparation of an octakis­(bromo) compound, which can be used as a Pd(0)-catalyzed coupling partner with suitable organometallic compounds to install a range of groups in high yields at the peripheral 2,3,­6,7,14,­15,19,20 positions, including methyl, allyl, vinyl, alkynyl, aryl, heteroaryl, and even bulky 4-(triphenylmethyl)­phenyl substituents.
