rapid ketone hydrogenation should minimize this deoxygenation. A dual catalyst approach based on these insights has been developed, with both Pd/Pt and Ru/Pt catalyst systems as more selective than Pd-only systems. Based on reaction profiles that indicate the deoxygenation side reaction is first-order in the concentration of debenzylated ketone intermediate, Pt catalysts for rapid and selective ketone
