The enol and keto forms are said to be tautomers of each other, and the interconversion of the two forms involves the movement of an alpha hydrogen and the shifting of bonding electrons.
At what temperature does tautomerization stop? (E.g I can obtain both the enol and keto form without them interconverting)
To make this simple, let's just assume the molecule of choice is: acetaldehyde
In addition there is no tunneling of the two tautomers. Lastly it is known the the two tautomers of acetaldehyde are stable and do not convert at 11 K with argon matrix trapping. What's the highest temperature that do not interconvert?
