Abstract
Pyrolysis of indanetrione
at 500-800� produces benzyne, which was detected by its reaction with benzene
and with chlorobenzene and, in pyrolyses in vacuo, by
the formation of biphenylene and triphenylene. The isolation of the carbonyl compounds
benzocyclobutenedione, fluorenone, anthraquinone, and
phenanthrene-quinone from some pyrolyses suggests
that loss of carbon monoxide occurs in successive steps which parallel those in
the mass spectral fragmentation of the indanetrione
molecular ion. A species having the composition of benzocyclopropenone
(X) may be involved in the formation of fluorenone, anthraquinone, and phenanthrenequinone.
