THE PHOTOCHEMICAL PREPARATION OF OZONIDES BY ELECTRON-TRANSFER PHOTO-OXYGENATION OF EPOXIDES

9,10-Dicyanoanthracene (DCA) sensitizes the electron-transfer photo-oxygenation of epoxides in oxygen-saturated acetonitrile to form ozonides.Epoxides with oxidation potentials lower than 2 V vs SCE quench the fluorescence of DCA and are converted to the

PHOTO- AND THERMOINDUCED GENERATION OF 1,3-DIARYL CARBONYL YLIDES FROM 2,3-DIARYLOXIRANES. 1,3-DIPOLAR CYCLOADDITIONS TO DIPOLAROPHILES

A group of symmetrically substituted 2,3-diaryloxiranes have been studied as photoprecursprs for carbonyl ylides.The stereochemistry of the adducts obtained upon interception of these 4n pi-transient systems with a variety of dipolarophiles provides information on the mode(s) of electrocyclic opening of the oxiranes to carbonyl ylides, as well as the mechanism of the 4n+2 cycloaddition process.The stereochemistry of the dipolarophiles is preserved in the cycloadducts, which is consistent with a concerted addition process; however, solvent effects, steric hindrance, and possibly secondary orbital overlap factors all may play a role in determining the product distribution.
