Abstract

1,129,623. Cyclohexane diones. EASTMAN KODAK CO. 24 Jan., 1966 [22 Jan., 1965], No. 3053/66. Heading C2C. [Also in Division G2] Cyclohexane diones of the formula wherein R<SP>8</SP> and R<SP>6</SP> are H, alkyl, aryl (substituted or unsubstituted), cyano or carbalkoxy and R<SP>4</SP> and R<SP>6</SP> are H, alkyl or aryl (substituted or unsubstituted) are prepared by the condensation of α.#-unsaturated ketones with malonic acid esters, cyano acetic acid esters or aryl acetic acid esters, carbalkoxy groups being removed by hydrolysis and decarboxylation. A specific compound prepared is 5,5-dimethyl cyclohexane-1,3 dione.
