    Description / Table of Contents: Starting from 1,4-bis-(3-iodopropyl)-2,5-dimethoxybenzene (3) via the reaction to the corresponding bis(1,3-dithian-2-yl) compound 4 and its double alkylation by 3 the 22-membered ring system of 5 was obtained from which 9,12,22,25-tetramethoxy[7.7]paracyclophane-4,17-dione (1) was prepared. The molecular structure of 1 is discussed on the basis of an X-ray analysis.
    Notes: Ausgehend von 1,4-Bis(3-iodpropyl)-2,5-dimethoxybenzol (3) wurde über die Reaktion zu der entsprechenden Bis(1,3-dithian-2-yl)-Verbindung 4 und deren erneute doppelte alkylierung durch 3 das 22-gliedrige Ringsystem von 5 aufgebaut, aus dem 9,12,22,25-Tetramethoxy[7.7]paracyclophan-4,17-dion (1) erhalten wurde. Die Molekülstruktur von 1 wird auf der Grundlage einer Röntgen-Strukturanalyse diskutiert.
