- •
The highest conversion with high selectivity to debenzylation was observed for Pd/C.
- •
Debenzylation is promoted by acid buffer while basic buffer suppresses the reaction.
- •
Dissociative hydrogen and substrate are adsorbed on different types of active sites.
- •
Aniline is produced primarily by defluorination of 4FA.
- •
Defluorination of 4FA is not catalyzed by Pd/C under studied conditions.
