Abstract: A stereochemical test was conceived to determine if the photochemical extrusion of carbon monoxide from 3, 5-cycloheptadienones to give 1, 3, 5-hexatrienes is a concerted process, and thus an example of a photochemical cheletropic fragmentation. The cis-and trans-2, 7-dimethyl derivatives of this ring system were synthesized. Spectroscopic data could not distinguish unambiguously between the two materials, and configurations were ...
