FLUORINATED PHOSPHONIC ACIDS

Fluorinated phosphonic acid compounds, useful as treatments for substrate surfaces, have the formula (I) : wherein: R?1? is a straight chain alkylene group having from 3 to 21 carbon atoms, an oxa-substituted straight chain alkylene group having from 2 to 20 carbon atoms, or a thia-substituted straight chain alkylene group having from 2 to 20 carbon atoms; R?2? is a perfluoroalkyl group having from 4 to 10 carbon atoms; R?3? is hydrogen, an alkali metal cation, or an alkyl group having from 1 to 6 carbon atoms; and M is hydrogen or an alkali metal cation, with the proviso that if R?1? is an unsubstituted straight chain alkylene group, then the sum of carbon atoms in R?1? and R?2? combined is at least 10.

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

New fluorinated thiols R(F)(CH2)(p)SH and disulfides [R(F)(CH2)(p)S]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. (C) 2000 Elsevier Science Ltd.
