[摘要]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 D2O at 180 degrees C under a H-2 atmosphere, and a synergistic effect was observed in relation to the incorporation of deuterium at sterically hindered positions on aromatic rings.
