2-Chlorotetrafluorocyclobutenyl copper reagent was prepared via copper(I) bromide metathesis from the corresponding zinc reagent which was readily obtained from 1-chloro-2-iodo-3,3,4,4-tetrafluorocyclobutene by the direct reaction with zinc metal in DMF.The copper reagent was used to synthesize alkyl and acyl derivatives of tetrafluorocyclobutene.
