Autocondensation of Cyclic Ketones

The reactions of cyclohexanone and 2-, 3-, and 4-methylcyclohexanones, cyclopentanone, and cycloheptanone, mainly under the action of acid and alkaline reagents, have been examined. The conditions governing the formation and the structures of the dimeric, trimeric, and polymeric autocondensation products — αβ-,βγ-, and other unsaturated ketones, hydroxyketones, compounds with furan or hydrogenated furan rings, dihydropyrans, hydrocarbons such as dodecahydrotriphenylene, and other compounds — have been discussed. The bibliography includes 102 references.
