4,12-Bis(2,2-dibromovinyl)[2.2]paracyclophane

Résumé

In the title compound, C20H16Br4, both vinylic substituents were introduced by a Corey-Fuchs reaction using 4,12-diformyl[2.2] paracyclophane as starting material. The title compound may be used as a valuable precursor for the synthesis of diethynyl[2.2] paracyclophane. The title molecule is centrosymmetric with a crystallographic center of inversion between the centers of the two phenyl rings. A strong tilting is observed with an interplanar angle between the best aromatic plane and the vinyl plane of 49.4 (5)degrees. No significant intermolecular interactions are found in the crystal.
