Relief of strain is the driving force for the [2 + 2] cycloaddition and subsequent [2 + 2] cycloreversion of 1 with both open‐chain and cyclic alkenes. The metathesis can even be performed with benzene as the olefin component [Eq. (a)]. The product can be roughly described as a ribbon‐ or beltlike conjugated system.
