Cyclopentindene (Benzopentalene) and Pentalene: Pyrolytic Formation from 3-Phenyl- and 3-Vinyl-phthalic Anhydrides

Pyrolysis of 3-phenylphthalic anhydride at 900 deg/0.02 mm gives cyclopentindene, characterized by 1H n.m.r. at -70 deg and by formation of a cyclopentadiene adduct and of a dimer at room temperature.Pyrolysis of 3,4-, 3,5- and 3,6-diphenylphthalic anhydrides also gives much cyclopentindene by loss of the additional phenyl group. 3,4-diphenylphthalic anhydride forms triphenylene as the major product.The pyrolysate from 3-vinylphthalic anhydride contains the known dimer of pentalene, and phenylacetylene.Pyrolyses of 3-(1-naphthyl)phthalic anhydride and of 4-phenylphenanthrene-2,3-dicarboxylic anhydride are described.
