✦ Synopsis

Study of Reactive Intermediates in Photoinduced Electron Transfer anti-Markovnikov Addition of Methanol to 1-Phenylcycloalkenes.

-The isomer ratio in the title reaction is investigated for the first time based on mechanistical studies by means of fluorescence spectroscopy, pulse radiolysis and semiempirical molecular orbital calculations (PM3). The ratio of (III) and (IV) in acetonitrile depends on the structures and stabilities of the radicals and carbanions. In benzene the cis-addition of MeOH to (I) predominates due to exciplex-formation between (I) and the sensitizers.
