    Notes: ---The condensation of substituted diiminoisoindolines with alkyl-substituted 1,3,3-trichloroisoindolines results in the formation of the highly soluble metal-free phthalocyanines 9, 15. By the same methodology, metal-containing phthalocyanines such as 16, 18 are accessible from suitable metal salts. The precursors 24 and26 were obtained from the phthalocyanine 9 and tetracyclone. The generation of the phthalocyanines 23 and 25 possessing isobenzofuran moieties as diene subunits was accomplished; in the presence of excess 28, the tetracyclone-bisadducts 22 and 24 were transformed into the model compounds 29 and 30, while an excess of 20 or 9 leads to the appropriate trimer-oligomers 31 and 32.

    Synthesis of a Bisdienophilic Phthalocyanine and of Precursors for Repetitive Diels-Alder Reactions Based on Hemiporphyrazines and Phthalocyanines (1997)

    Notes: The specific synthesis of a metal-free bisdienophilic phthalocyanine 193, suitable for repetitive Diels-Alder reactions, is reported. This was achieved by condensation of 191,3,3-trichloro-6/7-nitroioindolenine (191) and 4,9-dibutoxy-2,3,5,8-tetrahydro-1,3-diimino-1H-5,8-epoxybenz[f]isoindoline (2). The ability of 3 to undergo Diels-Alder reactions was tested by reaction with an excess of 1,2,3,4-tetraphenylcyclopentadienone (5). Experimental data of the hemiporphyrazines 9, 10, and 11, which can be used as precursors for the synthesis of ladder polymers, are also given in the Experimental Section.
