Examples of Specific Solvent Effects

Transition state more strongly solvated In solvent B, reactivity enhanced In solvent B [Pg.362]

Ground state more strongly solvated in solvent B, reactivity decreased in solvent B [Pg.362]

Crown Ether and Phase Transfer Catalysts Particularly striking examples of the effect of specific solvation occur with the crown ethers. These macrocyclic polyethers specifically solvate cations such as Na+ and K+. [Pg.363]

When added to nonpolar solvents, the crown ethers increase the solubility of ionic materials. For example, in the presence of 18-crown-6, potassium fluoride is soluble in benzene and acts as a reactive nucleophile  [Pg.364]
