摘要:The invention relates to a novel method for producing nucleophilic substitutions, particularly of type SNAr and SN2. More specifically, the invention relates to the use as a fluorinating reaction medium of ionic liquid or fused salt comprising at least four carbon atoms. The invention can be used for the synthesis of fluoride derivatives.
