Abstract
Although nucleophilic substitutions that use metal salts as nucleophiles are crucial synthetic transformations, these reactions, especially fluorinations,[1] often proceed sluggishly because of the limited solubility and low nucleophilicity of metal salts in organic solvents.[2] Phase-transfer catalysts such as crown ethers [3] and quaternary ammonium or phosphonium salts [4] have been used to enhance the solubility and nucleophilicity of the ...
