Mechanistically Significant Details of the H/D Exchange Reactions of Propene over Acidic Zeolite Catalysts

Quid pro quo: Hydrogen–deuterium exchange of propene on solid acid catalysts was studied at 573 and 673 K with a reaction time of 3 s (see scheme). At low partial pressures and temperatures, H/D exchange produced [D5]propene as the main product. Complete deuteration ([D6]propene) was observed only a...

Summary:Quid pro quo: Hydrogen–deuterium exchange of propene on solid acid catalysts was studied at 573 and 673 K with a reaction time of 3 s (see scheme). At low partial pressures and temperatures, H/D exchange produced [D5]propene as the main product. Complete deuteration ([D6]propene) was observed only at a higher temperature with the most acidic catalyst.
