Photochemical cycloadditions of cyanoacetylene and dicyanoacetylene were used to prepare all three isomeric tricyanobenzenes and various tetracyanocyclooctatetraenes 435-439. Yields were extremely low Cycloadditions were also performed with [6]paracyclophane to afford a [2 + 2]adduct, and with naphthalenophane and anthracenophane to give [2 + 2]adducts. ... [Pg.851]

To prepare 5-AI or 3-AI, hydroxylamine or /V-hydroxyurea may be used as synthetic equivalents of the NO-synthon and malonodinitriles, p-ketonitriles and cyanoacetylenes, as equivalents of the C3-synthon. The condensation of... [Pg.195]
