Ozonolyses of the vinyl ethers 1a-f in methanol afforded almost exclusively the corresponding α-methoxy hydroperoxides 4, suggesting the preferred formation of the carbonyl oxides 2.In aprotic solvents including methyl formate, the predominant modes of decay of the carbonyl oxides 2 were cyclodimerization, reduction, and rearrangement, yet no ozonide formation.By contrast, ozonolyses of 1a-f on polyethylene gave the α-methoxy-substituted ozonides 14 in fair yields.Ozonolyzes of 1a-f in the presence of added carbonyl compounds 6 in methylene chloride or ether yielded the corresponding cross ozonides.Judged from the ozonide yields, the reactivities of the carbonyl compounds follow the sequence: (ClCH2)2C=O > ClCH2COCH3 > (CH3)2C=O and 2-CF3C6H4CHO > PhCHO.

Irradiation of the electron donor-acceptor (EDA) complexes of 2,2-diaryl-1-methylenecyclopropanes, 1,1,2,2-tetraarylcyclopropanes, 2,3-diaryloxiranes, or 2,3-diarylaziridines with tetracyanoethylene (TCNE) under aerated conditions involved oxygenation and
Stereoselective Oxygenation of 2,3-Diaryloxiranes by Irradiation of Electron Donor-Acceptor Complexes of Tetracyanoethylene

On irradiation of the electron donor-acceptor complexes of 2,3-diaryloxiranes with tetracyanoethylene (TCNE) in the presence of oxygen, cis-trioxolanes are formed stereoselectively; a nonstereoselective cycloaddition with TCNE competes with trioxol

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
