Notes:
Dye-sensitized photooxygenations of 3 pairs of (E)/(Z) trisubstituted olefins were studied in order to establish the partitioning between the 3 possible ene additions. The (E)-isomers underwent only the 2 ene additions (〉95%) involving H-atom abstractions at the same, disubstituted side of the olefins, termed syn ene additions, with almost equal ease. The (Z)-isomers underwent mainly (85-90%) the syn ene additions, with the ones leading to the tertiary hydroperoxides distinctly favoured, and some (10-15%)ene additions at the monosubstituted side of the olefin, termed anti ene addition.
