    Description / Table of Contents: Monosubstituted [16] AnnulenesThe syntheses of methoxycarbonyl- (4a ⇌ 5a), phenyl- (4b ⇌ 5b), Chlor- (4c ⇌ 5c) and fluoro[16]annulenes (4d ⇌ 5d) are described: The temperature dependent n. m. r. spectra of these compounds are reported and discussed using the exchange mechanism proposed for [16]annulene.
    Notes: Die Synthesen von Methoxycarbonyl- (4a ⇌ 4a), Phenyl- (4b ⇌ 5b), Chlor-(4c ⇌ 5c) und Fluor[16]annulenen (4d ⇌ 5d) werden beschrieben. Ihre temperaturabhängigen NMR- Spektren werden mitgeteilt und im Lichte des für [16] Annulen entwickelten Austauschmechanismus diskutiert.

    Description / Table of Contents: Preparation and Valence Tautomerism of FluorocyclooctatetraeneTreatment of bromocyclooctatetraene with silver fluoride in pyridine yields 67% fluorocyclo-octatetraene. Its Diels-Alder reactions take place via the valence-tautomeric bicyclo[4.2.0]-octatriene structure. While the tetracyanoethylene adduct is derived from 7-fluorobicyclo-octatriene, azodicarboxylic acid phenylimide and methylimide intercepts exclusively with 1-fluorobicyclooctatriene.
    Notes: Die Umsetzung des Brom-cyclooctatetraens mit Silberfluorid in Pyridin liefert 67% Fluor-cyclooctatetraen, dessen Diels-Alder-Reaktionen über die valenztautomere Bicyclo[4.2.0]-octatrien-Stufe stattfinden. Das Tetracyanäthylen-Addukt leitet sich vom 7-Fluor-bicyclo-octatrien ab, während mit Azodicarbonsäure-phenylimid und -methylimid ausschließlich das 1-Fluor-bicyclooctatrien abgefangen wird.

    Description / Table of Contents: Substituted 1-Indancarboxylic AcidsHalogenations or carboxylations of 1-indancarboxylic acid (3a) and its esters 3b, c lead to the 6-halogen derivatives 4a and Sa or to the 6-indancarboxylic acid 9. Nitration of 3a and of 4a, respectively, yields nitro-1-indancarboxylic acids 6 and 7 (mixed with 6) and 10a, 11, respectively, which are reduced to the corresponding amino compounds 8,12a, 13 or 17a. Table 1 shows the 1H-NMR data of the substitution products 4-7, 9-11 and of 5-nitro-1-indan-carboxylic acid (18; from 12a). - 6-Phenoxy- (19a), 6-anilino- (ZO), 6-thenoyl- (24), 6-benzoyl- (25a), and l-(l-oxo-2,3-dihydro-2-isoindolyl)indancarboxylic acids 22a- d (Table 2) are synthesized as potential anti-inflammatory compounds.
    Notes: Halogenierung und Carboxylierung der 1-Indancarbonsäure (3a) und ihrer Ester 3 b, c führt zu den 6-Halogenderivaten 4 a und 5a bzw. zur 6-Indancarbonsäure 9. Nitrierung von 3a und 4a ergibt die Nitro-1-indancarbonsäurederivate 6 und 7 (im Gemisch mit 6) bzw. 10a und 11, die zu den entsprechenden Aminoverbindungen 8, 12a, 13 oder 17a reduziert werden. Die 1H-NMR-Daten von 4-7 und 9-11 und von 5-Nitro-I-indancarbonsäure (18; aus 12a) zeigt Tabelle 1.- 6-Phenoxy- (19a), 6-Anilino- (20), 6-Thenoyl- (24) und 6-Benzoyl- (25a) sowie l-(l-Oxo-2,3-dihydro-2-isoindolyl)indancarbonsäuren 22a - d(Tabelle 2) wurden als mögliche Entzündungshemmer synthetisiert.
