摘要：

The fourfold clamped title hydrocarbon 5, the biphenylene unit of which is strongly deformed out of plane, was obtained in 13% yield via sulfone pyrolysis; the X-ray analysis demonstrates that the framework of the biphenylene unit is bent out of planarity up to 18.7-degrees due to transannular repulsion, whereas the C-C bonds of the four ethano bridges are elongated compared with reference compounds.
