Cosolvents can affect catalytic reactions in several ways:
Solvent effects: They can alter the polarity of the reaction medium, which can influence the solubility and reactivity of the reactants and catalysts. Stabilization of intermediates: Cosolvents can stabilize charged or polar intermediates, thus facilitating certain reaction pathways. Rate enhancement: Improved solubility and stabilization of intermediates can lead to an increase in reaction rates. Selectivity: By modulating the reaction environment, cosolvents can enhance the selectivity towards the desired product.
