Palladium catalyzed reaction mechanism
WebJul 15, 2024 · In general, palladium-based catalysts are involved in a variety of organic reactions, such as alkylation, arylation, cyclization, hydrogenation, oxidation, … WebMar 7, 2016 · The results show that FAD catalyzed by one Pd atom follows a different mechanism compared with that catalyzed by surfaces or larger clusters. At the initial stage of the reaction, FAD follows a dehydration route and is quickly poisoned by CO due to the formation of very stable PdCO.
