We report a new reaction cascade allowing preparation of synthetically important isatin-hydrazones by the reaction of detrifluoroacetylatively in situ generated 3-fluoroindolin-2-one enolates with diethyl azodicarboxylates. The reactions take place under operationally convenient conditions featuring synthetically attractive chemical yields. Plausible mechanistic rationale is discussed.
