Photochemistry of 4-Methoxybicyclo[3.1.0]hexenones.

-A detailed mechanistic study of the photochemistry of bicyclic compounds (I) and (II), in combination with computational studies, points to a reasonable mechanism for the observed wavelength-dependent phenol formation. The crucial factor for achieving wavelength dependency is the 4-methoxy substitution pattern, which drastically lowers the π→π* triplet state. As a result, two competing processes, i.e., photoisomerization and phenol formation, become apparent. - (DAUBEN,
