Photochemical Rearrangement of 2-Substituted 4-Alkylidene-2,3-epoxy-1-tetralone to 3-(2-oxoalkylidene)-1-indanone

10.1246/cl.1986.1849

The research investigates the photochemical rearrangement of 2-substituted 4-alkylidene-2,3-epoxy-1-tetralone to 3-(2-oxoalkylidene)-1-indanone. The purpose is to explore the photoreactions of α,β-epoxy ketones and understand the factors determining their reaction pathways. Key chemicals used include 2-substituted 4-methylidene-2,3-epoxy-1-tetralones (1a-e), benzene, and Wittig reagent. The study found that irradiation of these compounds in benzene solution under an argon atmosphere led to the formation of 3-alkylidene-1-indanones (2a-e) with yields ranging from 27% to 56%. The photoreactions are suggested to occur from the (π, π*) triplet excited state. The research concludes that the nature of the excited state and the localization of excitation energy in the starting molecules significantly influence the reaction outcomes.
