%X Flash vacuum pyrolysis of the 3-phenylindol-2-ylmethylene derivative (12) of Meldrum's acid at 600&#176; and at 750&#176;/0.03 mm gives 9-phenyl-3H-pyrrolo[1,2-a]indol-3-one (14) (97%). At 900&#176;/0.3 mm (14) (49%) is accompanied by 7H-benzo[c] carbazole (6) (10%). The latter is formed by intramolecular C-H insertion in the title carbene (5).
