Perfluoroalkylation in flow microreactors: generation of perfluoroalkyllithiums in the presence and absence of electrophiles

Abstract

Perfluoroalkyllithiums were effectively generated from perfluoroalkyl halides in the presence and absence of electrophiles using flow microreactor systems. The in situ trapping with electrophile is conducted at much higher temperatures than those required for batch macro reactors. The subsequent trapping method is quite effective for highly reactive electrophiles that are not compatible with the lithiation process.
