Notes:
The flash vacuum pyrolysis and the photolysis of 2,3-thiophenedicarboxylic acid anhydride (6) were investigated by using the technique of matrix isolation combined with FT-IR spectroscopy. No conclusive proof for the existence of 2,3-didehydrothiophene (1) could be found, but two hitherto unknown isomers were isolated and characterized: vinylidenethioketene (10) and thioformylvinylidenecarbene (15).
