Conjugated Unsaturated Ketones. III. Aromatization‐Like Reactions and Aromatization of Dibenzalcycloalkanones

Abstract The stability of 2,6‐dibenzalcyclohexanone (V) and 2,5‐dibenzalcyclopentanone (VI) has been discussed. Twenty‐seven examples of aromatizationlike reaction of 2,6‐dibenzalcyclohexanone and 2,5‐dibenzalcyclopentanone have been studied. Aromatization of 2,6‐dibenzalcyciohexanone has been realized by both indirect and direct methods.
