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

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 molecul...
