Ion cyclotron resonance techniques show that in the gas phase the oxygen exchange reaction in the system OH–+ HC(18O)(OMe) is at least 10–2 times slower than the hydrolysis reaction; this result, plus thermochemical estimates, suggest that the tetrahedral adduct HC(OMe)(OH)O– is more likely a local transition state rather than a stable intermediate.
