The pyrolyses of acenaphthenoneketazine (I) and acenaphthenone N-benzoylhydrazone (II) were investigated in order to elucidate whether the Pilotz-Robinson reaction product (III) is formed or not. It has been found that the pyrolysis of I afforded ammonia, 2,3-dihydro-6H-triacenaphtho [1,2-b, -d, -f] azepine (IV), decacyclene (V) and acenaphthazine (VI) ; although a large amount of resinous material was formed, III was not obtained. On the other hand, III was not also obtained in the pyrolysis of II, but 2-phenyldiacenaphtho [1,2-c, -e] pyridine (VIII), acenaphthopyridazine (IX), benzamide (X) and N, N'-dibenzoylhydrazine (XI) were also obtained, besides IV, V and VI. The structures of these products were confirmed by direct comparison with the samples prepared by unequivocal routes, or by ultraviolet, infrared, nuclear magnetic resonance and mass spectral studies. The processes of the products formation are also discussed.
