Abstract We prepared several activated carbon-supported bimetallic Pd-Pt catalysts (Pd- Pt/C) by using various reducing reagents, and examined their catalytic activities for the deuteration of alkyl-substituted aromatic compounds. Multiple deuterations catalyzed by Pt- Pd/C proceeded in D 2 O at 180 C under a H 2 atmosphere, and a synergistic effect was observed in relation to the incorporation of deuterium at sterically hindered positions on ...
