Aryl‐ and heteroarylcyclobutenone rearrangements proceed in excellent yield under continuous‐flow conditions. The former shows a Hammett correlation with σI providing strong evidence that electrocyclisation is the rate‐determining step and has a late transition state. The reaction has been modelled by using DFT and CCSD(T) methods, with the latter giving excellent correlation with the experimental
