Cycloparaphenylenes 3 bearing ten aromatic units in the macrocyclic structures ([10]CPPs) with internal phthalimido bridges were synthesized. The Diels−Alder reactions between bismaleimides 1 and two equiv of 1,3-butadiene 2 followed by the nickel−mediated intramolecular homocoupling reactions and oxidative aromatization produced [10]CPPs 3.
