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

In the title compound, C(20)H(16)Br(4), 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 i...

description In the title compound, C(20)H(16)Br(4), 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)°. No significant inter­molecular inter­actions are found in the crystal.
