The nitro complex (NH/sub 3/)/sub 5/CoNO/sub 2//sup 2 +/ reacts rapidly and completely with neat anhydrous trifluoromethanesulfonic acid to generate the aqua species (NH/sub 3/)/sub 5/CoOH/sub 2//sup 3 +/. Oxygen-17 NMR results show that the oxygen in the bound water is derived from the original nitro group. A mechanism involving acid-catalyzed nitrogen-to-oxygen nitrite rearrangement is considered. The relationship between the mechanisms for oxygen scrambling and acid-catalyzed loss of NO/sup +/ from the nitrito linkage isomer is discussed, together with the mechanism for the present reaction. 20 references, 1 figure.
