Why are Metal Carbene Complexes Important in Catalysis?
Metal carbene complexes are pivotal in catalysis due to their ability to mediate a variety of transformations, including cyclopropanation, olefin metathesis, and polymerization. These complexes can act as intermediates, facilitating reactions that are otherwise challenging under standard conditions. Their importance stems from their versatility and efficiency in promoting chemical reactions with high selectivity and yield.
