The Diels–Alder (DA) reaction of diacenaphtheno[1,2-b;1′,2′-d]thiophene (1a) with benzyne affords 1:1 and 1:2 adducts, 7 and 8, in 47 and 11% yields. An X-ray crystallographic analysis reveals that 8 possesses a dibenzobarrelene structure involving a rigi

With the aim of elucidating the mechanism of the thermochemical conversion of oligophenylenes containing acenaphthylenyl groups, the thermolysis of model compounds: 1,3,5-tris(5-acenaphthylenyl)benzene (1), 1,3,5-tris(5-acenaphthenyl)benzene (2), acenaphthylene, and acenaphthene, was studied by differential thermal analysis (DTA), dynamic thermogravimetric analysis (TGA), and mass spectrometry.Compounds 1 and 2 were studied by X-ray structural analysis.A scheme for the formation of secondary structures was suggested.Optimum temperature conditions were found for preparing thermostable, heat-resistant, and stable to thermooxidation polymers based on compounds containing the acenaphthylenyl groups. - Key words: 1,3,5-tris(acenaphthylenyl)benzene, 1,3,5-tris(acenaphthenyl)benzene, acenaphthylene, acenaphthene, thermochemical conversions; decacyclene; polymers, thermal properties; X-ray structural analysis.
