“…In conclusion, the present paper provides direct evidence for the dual-path mechanism described by scheme [I], where the "reactive intermediate" probably is COOHa~ and the "inhibiting intermediate" is HCO~d. Indirect evidence for the dual-path mechanism was recently given by Adzic (18) as well as by Pletcher (19). Unfortunately, however, the intermediate proposed in Eq.…”

Using either normal formic acid in H218O or 18O‐labeled formic acid in H216O , the following results were obtained: the oxygen atoms of formic acid are homogeneously exchanged with water; the strongly bound intermediate however does not exchange oxygen with water; the 18O‐labeled intermediate is oxidized in H216O to C18O16O by a three‐electron process; direct oxidation of HC16O16OH in H218O delivers C16O16O .
