A highly selective oxidative heterocoupling protocol for (hetero)aryl boronic acids with an active palladium colloidal catalyst was developed. The judicious choice of electronically different aryl boronic acids made possible such couplings under mild conditions, with air as oxidant, while embracing a wide substrate scope. This successful approach further allowed the development of a unique one-pot sequential oxidative heterocoupling/Suzuki–Miyaura cross-coupling tandem process for accessing substituted terphenyls.

Oligo-p-phenylenes have proven to be versatile building blocks for the generation of self-assembled nanoaggregates with interesting optical properties via vapor deposition on solid supports. Preliminary studies have shown that both the properties and the morphologies of these aggregates can be influenced by the introduction of functional groups. To this end, we have developed general approaches to the synthesis of symmetrically and unsymmetrically 1,4?-substituted p-quaterphenylenes through the application of a reliable Suzuki cross-coupling strategy.
