Abstract The synthesis of a [1.1.6] metapara cyclophane derivative, 1,5(1,4),3(1,3)‐tribenzenacycloundecaphan‐8‐ene‐6,11‐dione, has been achieved via the Suzuki–Miyaura cross‐coupling of α,α′‐dibromo‐ m ‐xylene with an arylboronic acid derivative followed by an allylation and ring‐closing metathesis reaction sequence.
