The photolysis of 1-acetylcyclooctene in acetonitrile solution leads to 3-(α-hydroxyethylidene)cyclooctene (two stereoisomers). Structures of the stable 1,3-dienols have been elucidated on the basis of their spectral data and chemical behavior. The dienols are highly air-sensitive. Upon heating, or by the action of an acid or base, they are converted to 3-acetylcyclooctene. In methanol-O-d, 3-acetylcyclooctene-3-d
