called tautomerization. This
conversion commonly results from the
relocation of a

- tautomerism,
although this name is
often more
generally applied to all such
tautomerizations.
Usually the

Under normal conditions,
vinyl alcohol converts (
tautomerizes) to acetaldehyde: At room temperature,
acetaldehyde (H3CC(O)H) is more...
- Hg}}} The
mechanism involves the
intermediacy of
vinyl alcohol,
which tautomerizes to acetaldehyde. The
reaction is
conducted at 90–95 °C, and the acetaldehyde...
- then
nitrosated with
sodium nitrite; the
initial product spontaneously tautomerizes to

which have a
ketone group.
Ketoses must
first tautomerize to
aldoses before they can act as
reducing sugars. The

- compounds, the
protons on the α-carbon are

Enolization is an
