What are the Challenges in Using Metal Carbene Complexes?
Despite their advantages, there are several challenges associated with the use of metal carbene complexes in catalysis:
- Stability: Some metal carbene complexes can be sensitive to air and moisture, requiring stringent handling conditions. - Toxicity: Certain metals used in these complexes, such as chromium and molybdenum, can be toxic, posing environmental and health risks. - Cost: The synthesis of metal carbene complexes often involves expensive starting materials and reagents, which can limit their practical applications.
