Platinum on Carbon??Catalyzed H–D Exchange Reaction of Aromatic Nuclei due to Isopropyl Alcohol??Mediated Self??Activation of Platinum Metal in Deuterium Oxide
Abstract An efficient and simple deuteration method of arenes using the platinum on carbon- isopropyl alcohol-cyclohexane-deuterium oxide combination under hydrogen gas-free conditions was accomplished. Since the hydrogen–deuterium exchange reaction cannot be promoted without isopropyl alcohol, zerovalent platinum metal (on carbon) is self-activated by the in situ-generated very low amount of hydrogen or hydrogen–deuterium gas derived ...
