Abstract : The document is a final report of a project whose general goal was to discover new knowledge about the mechanism of heterogeneous catalytic hydrogenation (Deuteriogenation). Specifically, it was proposed to use (+)-1,3-dimethyl-cyclohexene and its isomers as molecular probes of the catalytic surface. By comparing the amounts of exchange and optical purity of both the recovered desorbed olefin and trans product it was anticipated that a choice could be made between the various surface intermediates which have been proposed in the literature. Although progress was made on preparing and purifying (+)-1,3-dimethylcylohexene, other pathways were found which yielded valuable information of similar nature and these were largely pursued during the grant period. These pathways included the hydrogenation and exchange of 2-pinene and 6,6-dimethyl-2-norpinene (apopinine). Also discussed are the catalytic hydrogenation and exchange of styrenes with tris(triphenylphosphine)-chloro rhodium. (Author)
