Cyclobutanol

Cyclobutanol is an organic compound with the chemical formula C4H8O; it is defined as a cyclobutyl group with a hydroxyl group pendant and thus a cycloalkanol. Physically, it is a yellowish clear liquid that crystallizes orthorhombically at low-temperatures.

Cyclobutylamine's Demjanov rearrangement with nitrous acid gives cyclobutanol, and cyclopropylmethanol rearranges in strong acid to the same. Metal hydrides reduce cyclobutanone to cyclobutanol; conversely, cyclobutanol oxidation is a salt-free route to cyclobutanone.
