The synthesis of a minimally fluorous (52% F) diaryl diselenide is described. On reduction in situ with tributylstannane this diselenide provides a fluorous selenol which is effective in inhibiting a range of stannane-mediated radical rearrangements, including a cyclopropylcarbinyl ring opening. A method for the recovery of the fluorous diselenide involving continuous extraction in a modified, cooled continuous extractor is described.
