  Kinetics and Mechanism of Oxygen Atom Abstraction from Sulfenatocobalt(III) Complexes by Hydrated Methyldioxorhenium(V)

  摘要：

  Cationic sulfenatocobalt(III) complexes, with the remaining ligands amines, are deoxygenated upon reaction with hydrated methyldioxorhenium(V). The reactions of (Am)(5)Co-S(O)R2+ yield the thiolato complexes (Am)(5)Co-SR2+ and methyltrioxorhenium(VII), MTO. A kinetic study of these reactions was carried out, using the known reaction between MTO and hypophosphorous acid to prepare the Re(V) reagent in solution. The second-order rate constants between (Am)(5)Co-S(O)R2+ and MeReO2(aq), after correction for protonation, fall in the range 47-455 L mol(-1) s(-1) in aqueous solution at 25.0 degrees C and 1.0 M ionic strength. In the analysis of the pH effects, allowance was made for the formation of the protonated species (Am)(5)Co-S(OH)R3+ at high [H3O+]. The values of pK(a) are in the range 0.49-0.96, as determined from fitting the rate-pH profiles.
