The impact of dppe on catalytic activity can be explained through several factors:
- Electronic Effects: The electron-donating nature of the phosphine groups can enhance the electron density on the metal center, making it more reactive. - Steric Effects: The spatial arrangement of the phenyl groups can influence the accessibility of the metal center, affecting the overall reaction rate. - Chelation: The formation of a stable chelate ring can increase the robustness of the catalyst, often leading to higher turnover numbers and longer catalyst lifetimes.
