The replacement of toxic organic solvents is one of the most important issues in green chemistry [1], [2] and [3]. Their use in organic synthesis inevitably leads to solvent emissions and/or waste. Especially, fluorination reactions have been recognized as being useful in organic synthesis, their reactions commonly employ organic solvents (such as DMF, CH 3 CN, DMSO, etc.), and in many cases they are removed from the final reaction mixture by a ...
