    Description / Table of Contents: On hydrogenation of the title compound 1 with Pd/C 1,4-diethylbenzene (2) is formed in 95% yield, furthermore 1% of cis- and 2% of trans-1,4-diethylcyclohexane (3 und 4) as well as 2% of 6-ethylspiro[2.5]octane (15) are found. With Pt/C the intermediates 7, 12, 13, and 14 and up to 45% of dispiro[2.2.2.2]decane (17) are identified. 17 is hydrogenated with PtO2 in acetic acid to form 1,1,4,4-tetramethylcyclohexane (19).
    Notes: Bei der Hydrierung der Titelverbindung 1 mit Pd/C entsteht zu 95% 1,4-Diethylbenzol (2), daneben noch ca. 1% cis- und 2% trans-1,4-Diethylcyclohexan (3 und 4) sowie 2% 6-Ethylspiro-[2.5]octan (15). Mit Pt/C wird zusätzlich (bis zu 45%) Dispiro[2.2.2.2]decan (17) gebildet, und man erkennt die Zwischenstufen 7, 12, 13 und 14. Mit PtO2 in Eisessig wird 17 weiter zu 1,1,4,4-Tetramethylcyclohexan (19) hydriert.
