2- and 3-Furylketenes (18 and 20), 2- and 3-thienylketenes (19 and 21), and bis(2,5-ketenyl)thiophene (24) have been generated as observable reactive intermediates by photochemical Wolff rearrangements. Stabilization energies of the monoketenes 18–21 have been determined by DFT computations of isodesmic energy changes, and these ketenes are predicted to be modestly destabilized relative to phenylketene
