The Electrodeposition of Silver from Supercritical Carbon Dioxide/Acetonitrile

Cyclic voltammetry of silver coordination complexes in acetonitrile and in a single-phase supercritical carbon dioxide/acetonitrile (scCO(2)/CH(3)CN) system is reported. Five silver precursors are investigated: (1,5-cyclooctadiene)(hexafluoroacetylacetonato) silver(I) [Ag(hfac)(COD)], (hexafluoroace...

Sumario:Cyclic voltammetry of silver coordination complexes in acetonitrile and in a single-phase supercritical carbon dioxide/acetonitrile (scCO(2)/CH(3)CN) system is reported. Five silver precursors are investigated: (1,5-cyclooctadiene)(hexafluoroacetylacetonato) silver(I) [Ag(hfac)(COD)], (hexafluoroacetylacetonato)(triphenylphosphine) silver(I) [Ag(hfac)(PPh(3))], (perfluorooctanoato)bis(triphenylphosphine) silver(I) [Ag(CF(3)(CF(2))(6)CO(2))(PPh(3))(2)], tetrakis(triphenylphosphine) silver(I) tetrafluoroborate [Ag(PPh(3))(4)][BF(4)] and tetrakis(acetonitrile) silver(I) tetrafluoroborate [Ag(CH(3)CN)(4)][BF(4)]. Of these, [Ag(CH(3)CN)(4)][BF(4)] is found to be the most suitable for electrodeposition of silver from scCO(2)/CH(3)CN.
