What are Some Challenges Associated with Ring Structures in Catalysis?
While ring structures offer many advantages, they also pose challenges. The synthesis of complex ring-containing catalysts can be difficult and costly. Additionally, the stability of these rings under reaction conditions can be a concern. For example, the aromatic rings in some catalysts may undergo [deactivation]() through π-π stacking interactions or be susceptible to [oxidative degradation](). Therefore, designing robust ring-containing catalysts requires careful consideration of these factors.
