The oxidation of manganese by bis(fluorosulfuryl) peroxide (S2O6F2) in HSO3F allows the preparation of Mn(SO3F)3 and the ternary fluorosulfates M′2[Mn(SO3F)5] (M′ = K or Cs), with manganese oxidized to the +3 oxidation state. The oxidation of Mn2(CO)10 by S2O6F2, or the further oxidation of Mn(SO3F)2 by S2O6F2, in either the absence or the presence of HSO3F provides alternate routes to Mn(SO3F)3. Solutions of M′2[Mn(SO3F)5] in HSO3F are unstable and produce polymeric Mn(SO3F)2. Rhenium is oxidized to the +7 oxidation state, and a yellow oil of the composition ReO2(SO3F)3 is identified as one of the reaction products. The reaction of Re2O7 with S2O6F2 provides an alternate route to ReO2(SO3F)3. The metal carbonyl fluorosulfates Re(CO)5SO3F and Mn(CO)5SO3F are obtained from the reaction of Re(CO)5Cl and Mn(CO)5Br, respectively, with AgSO3F in CH2Cl2. Controlled pyrolysis of Mn(CO)5SO3F at ～70°C allows isolation of Mn(CO)4SO3F.
