Last of the cyclic vinyl cations: The simple solvolysis of cyclopent‐1‐enyl‐λ3‐bromane efficiently generates the highly strained cyclopent‐1‐enyl cation at room temperature (see scheme). The very high nucleofugality of the aryl‐λ3‐bromanyl groups are responsible for this unique unimolecular dissociation.
