- W3009162824 abstract "The direct and sensitized photochemical behaviour of cyclic and acyclic olefins is analysed. Cyclo-hexenes and cyclo-heptenes undergo photoprotonation in hydroxylic media, perhaps via a trans intermediate by both, direct and sensitized irradiation. But acyclic, exocyclic, and larger-ring cyclic olefins fail to undergo photoprotonation on either direct or sensitized irradiation. However, larger-ring cyclic and acyclic olefins as well as cyclo-hexenes and heptenes undergo slow isomerization to positional and skeletal isomers on direct irradiation in either protic or aprotic media. Tetraalkyl-substituted olefins shows unique behaviouron direct irradiation in alcoholic solvents which suggest the involvement of a cation radical intermediate. Mechanistic implications of these various types of photochemical behaviour are discussed. Keywords: Irradiation, photosensitizers, photoprotonation, isomerisation." @default.
