Convenient synthesis of thiols and disulfides in the polyfluorinated series incorporating a butylic spacer

New fluorinated thiols RF(CH2)pSH and disulfides [RF(CH2)pS]2 containing a butylic spacer (p=4) between the perfluorinated part and the thiol (or disulfide) function were easily obtained in good yields with a purity higher than 98%. This allows us to obtain homologues (p>4) for their use as synthetic intermediates or as constituents for molecular organized systems.
