Photo‐excited arenes have been found to initiate a substitution reaction in which the sulfonyloxy group of α‐sulfonyloxyketones is displaced, and the corresponding β‐arylketones are formed. Evidence is presented that the electronically excited arene need not be involved directly in the substitution step. It would seem to be more likely that upon interaction with the sulfonyloxyketone a reactive species derived from the latter is produced which is capable of aromatic substitution.
