Abstract
The synthesis of cyclophane derivatives through a sequence involving Suzuki–Miyaura cross‐coupling between α,α′‐dibromo‐m‐xylene and arylboronic acid derivatives, alkenylation and ring‐closing metathesis has been achieved. One of the cyclophanes was obtained by tandem isomerization and metathesis. Significant magnetic anisotropic effects on the intra‐annular hydrogen atoms were observed. (© Wiley‐VCH Verlag GmbH & Co.
