Abstract
Substituted cyclohexene-2-ones are prepared by reacting a cyanoethylated ketone, such as 1,1,1-tri-beta-cyanoethyl acetone, in a polar solvent, e.g., methanol or water, in the presence of a catalyst. The compounds formed are useful in the production of cyclic amino acids, esters, hydroxy acids, as modifiers and as hardeners for phenolic and epoxide resins and as additives for lubricating oils.
