α,β-Unsaturated carbonyl compounds and esters, cyclopropyl ketones, β-diketones, Schiff’s bases, and nitriles were irradiated in several alcohols in the presence of titanium(IV) chloride or uranyl chloride. In the titanium(IV) chloride-catalyzed reactions, the α-carbon atom of the primary alcohols underwent a bond formation, generally with the C=X (or C≡N) carbon atom of the substrates, while the bond

A 3-hydroxymethylcycloalkanol of the formula (1)
wherein Y1 represents a saturated aliphatic hydrocarbon group. The 3-hydroxyethylcycloalkanol can be obtained by subjecting a 3-formylcycloalkanone or 3-formylcycloalkenone to reduction.
Amended Abstract
The present invention relates to a 3-hydroxymethylcycloalkanol of the following formula (1), and a process for production of a 3-hydroxymethylcycloalkanol of the formula (1) by reduction of 3-formylcycloalkanone or 3-formylcycloalkenone.
In accordance with the present invention, 3-hydroxymethylcycioalkanol, which is useful as the starting material for the production of polymers, can be produced with high conversion and high selectivity.
