Abstract
The ring-chain tautomerism of spiro derivatives of 5-hydroxytetrahydrofuran was investigated by PMR spectroscopy. The position of the tautomeric equilibrium and the time required to establish it depend on the nature of the solvent, the temperature, and the substituents in the tetrahydrofuran ring.
