A how-to for hexaarylbenzenes

A lack of general methods for making multisubstituted benzene derivatives means that only a small fraction of the huge number of possible structures based on this ubiquitous building block have been explored. Now, a programmed synthesis of hexaarylbenzenes using C–H activation, cross-coupling and [4 + 2] cycloaddition reactions has been developed that can also be applied to tetraarylnaphthalenes and pentaarylpyridines.
