What are the Challenges Associated with Metal Carbene Complexes?
Despite their utility, metal carbene complexes pose several challenges: - Stability: Many metal carbene complexes are sensitive to air and moisture, requiring stringent handling conditions. - Selectivity: Achieving high selectivity in catalytic processes can be difficult, especially in complex molecular environments. - Toxicity and Cost: Some metal carbene complexes involve rare or toxic metals, raising concerns over environmental impact and cost.
