Essentials of Pharmaceutical Chemistry
Warfarin is an interesting compound in that, in addition to ionising, it exhibits keto
— enol tautomerism. This means that warfarin exists in two constitutional
isomeric forms (tautomers) that are in equilibrium with each other, although one
of the ...

Introduction to Spectroscopy
The most common type of tautomerism is keto–enol tautomerism, in which the
species differ mainly by the position of a hydrogen atom. keto enol In general, the
keto form is much more stable than the enol form, and the equilibrium lies
strongly ...

Tautomerism: Methods and Theories
Keto–enol tautomerism is usually slow on the NMR timescale, but if there are two
enol tautomers, they are normally in fast exchange. Thus equilibria can be
examined at room temperature but the enol–enol exchange (often in the solid
state ...
