Anisole yields both ortho- and meta-cycloadducts upon irradiation in the presence of 1,3-dioxole and 2,2-dimethyl-1,3-dioxole.The mode and the regio- and stereo-selectivities of these cycloadditions are rationalized on the basis of the exciplex-zwitterion mechanism.
SELECTIVITY AND CHARGE TRANSFER IN PHOTOREACTIONS OF ARENES WITH OLEFINS 1. SUBSTITUTION VERSUS CYCLOADDITION
Mattay, Jochen
, p. 2393 - 2404 (2007/10/02)
In photoreactions of arenes with olefins the mode of reaction strongly depends on the charge transfer between the starting materials.Substitution is preferred if the electron transfer becomes exergonic, i.e. if ΔG 0 according to the Rehm-Weller equation.In some special systems substitution is avoided by electron transfer-triplet formation.Various photoreactions which already have been described in the literature are discussed in view of this ΔG-correlation besides own experimental results.
