Ozonolyse von Enolethern, 8. Mitteilung 7. und 9. Mitt., s. [1].

Abstract: Ozonolysis of Enol Ethers. Part 8. Ozonation of (1-Methoxy-2-methylprop-1-enyl)-1,1'-biphenyl in Comparison with Related OxygenationsThe results of conversions of 4-(1-methoxy-2-methylprop-1-enyl)-1,1 '-biphenyl (19) with ozone and with dimethyldioxirane (6b) under −normal× and −inverse× conditions are compared with oxygenations by dioxygen under thermal and sensitized photochemical conditions, as well as with the photooxygenation of epoxide 17, formally derived from 19. Ozone consumption varies between 0.7 a… Show more

“…The marginal improvements in oxidative cleavage yields in the presence of oxygen, as well as the decline in the yields when the photolysis was carried out in the presence of nitrogen, lead us to believe that molecular oxygen was involved in the reaction. While singlet oxygen is known to form dioxetane rings with alkene via [2 + 2] cyclizations, it is unlikely to occur in this case, as there is no known source of singlet oxygen. The triplet oxygen has been shown to form an adduct with alkene radical cations, which can then cyclize to form a dioxetane radical cation ring .…”
