Abstract
Two different theories have been proposed for the mechanism of the disproportionation of six-membered ring olefinic compounds in the presence of a metal catalyst. Wieland suggested this reaction occured [sic] in tow distinct steps of dehydrogenation and hydrogenation. On the contrary, Bruade and Linstead believed in hydrogen direct transfer on the surface of the catalyst. However, more information was needed to understand in detail the mechanism of the disproportionation of six-membered ring olefinic compounds. The work of this thesis was concentrated on the reaction of limonene in the presence of palladium on charcoal at a temperature about 20 degrees below its boiling point. The disproportionation and racemization of limonene at this low temperature were investigated and discussed. The result of this investigation favored the mechanism proposed by Wieland.
