In the reaction of singlet oxygen with certain trisubstitutedalkenes, a strong preference for regioselectivity favoring hydrogen abstraction on that side of the olefin with one substituent has been recognized. These results are rationalized in terms of non bonded interactions and the lack of oxygen interaction with two allylic hydrogens in the same side of the double bond.

trisubstituted alkenes, hydroperoxidation withinzeolites occurs with a certain amount of regioselectivity. The oxidationwithinzeolites is accompanied by photodecomposition of the dye and the product hydroperoxides and acid catalyzed rearrangement of the alkenes. In order to understand the observed selectivity, ab initio and DFT calculations on model systems have been performed. The calculations

Perfluorocarbons are excellent alternatives to chlorinated solvents as non-toxic, non-ozone-depleting, inert reaction media for photooxidation reactions. Essentially quantitative yields of peroxide products are obtained and the perfluorocarbon solvents are easily recovered and recycled.
