A new reaction pathway (6π+2π) for the intramolecular photocycloaddition of a carbonyl substituted hexatriene
Abstract
The trienic primary product formed in the photochemical ring opening of the cyclohexadienic isodypnopinacolone follows two different photoreaction pathways: a [4π+2π] cycloaddition and a [6π+2π] reaction involving the conjugated carbonyl group.
