    Description / Table of Contents: Studies on the Chemistry of Isoindoles and Isoindolenines, XXXI. 4,5,6,7-Tetrachloro- and 4,5,6,7-Tetrabromo-2H-isoindolesThe crystalline 2H-isoindoles 4b are synthesized starting with substituted 2-methylsulfonyl-2,3-dihydro-1H-isoindoles 3 by base-induced elimination of methanesulfinic acid. Compared with the parent compound, a considerable thermal stabilization and chemical deactivation is caused by the halogen atoms at the carbocyclic system. The spectroscopic properties of the o-quinonoid hetarenes 4b have been investigated.
    Notes: Die kristallinen 2H-Isoindole 4b werden aus substituierten 2-Methylsulfonyl-2,3-dihydro-1H-isoindolen 3 durch Basen-induzierte Eliminierung von Methansulfinsäure synthetisiert. Die Halogenatome am carbocyclischen System bewirken - verglichen mit dem Grundkörper - eine beträchtliche thermische Stabilisierung und chemische Desaktivierung. Die spektroskopischen Eigenschaften der o-chinoiden Hetarene 4b wurden untersucht.
