The N/T ratio, i. e. the proportion of norcaradiene (N) versus tropilidene (T) endoperoxides in the cycloaddition of singlet oxygen with 7-substituted 1,3,5-cycloheptatrienes, decreases in the order p-ClC6H4 > C6H5 >p-MeOC6H4 and t-Bu > i-Pr > Et > Me, pr

Photooxygenation of 7-substituted cycloheptatrienes, including the Me, Et, iPr, Ph, CN, COOMe, COOEt, and CONH2 groups was studied, and several products among the tropilidene-type (1 and 2) and norcaradiene-type (3 and 4) endoperoxides, o-substituted benzaldehydes (5), diepoxides (6 and 7), and ketoalcohols (8) were obtained.Mechanism of the formations of the products was discussed.Thermal isomerization of the endoperoxides (1, 3 and 4) to the corresponding diepoxides (10, 6 and 7), and the reaction of the endoperoxides (1 and 3) with triethylamine were examined.
