Abstract

2-Methoxy-5-[3-(trifluoromethyl)phenyl]pent-1-ene undergoes 2,6- and 1,3-meta-photocycloaddition on irradiation (lambda = 254 nm). The methoxy group has the endo configuration in the photocycloadducts. Irradiation of the para- and ortho-CF3-substituted 2-methoxy-5-phenylpent-1-enes leads to intramolecular ortho-photocycloadducts. The difference inproduct formation is related to the free enthalpy of electron transfer.
