Hydrogenolysis of Small Cycloalkanes, XV. - Hydrogenation of Dispirodeca-4,9-diene

Kiwus, Regina,Schwarz, Wolfgang,Rossnagel, Ingrid,Musso, Hans

, p. 435 - 438 (2007/10/02)

On hydrogenation of the title compound 1 with Pd/C 1,4-diethylbenzene (2) is formed in 95percent yield, furthermore 1percent of cis- and 2percent of trans-1,4-diethylcyclohexane (3 and 4) as well as 2percent of 6-ethylspirooctane (15) are found.With Pt/C the intermediates 7, 12, 13, and 14 and up to 45percent of dispirodecane (17) are identified. 17 is hydrogenated with PtO2 in acetic acid to form 1,1,4,4-tetramethylcyclohexane (19).
