methyl-substituted aromatic hydrocarbons have revealed that whereas electron density is a determinant of endoperoxide formation, steric factors are most important in influencing the stability of the endoperoxide. Additional information on the energetics of the reactions and on the magnitude of the steric interactions was obtained using calculations at the B3LYP/6-311+G* level of theory.
关于甲基取代的芳烃的光氧化的研究表明,尽管电子密度是内过氧化物形成的决定因素,但空间因素在影响内过氧化物的稳定性方面最重要。使用理论上的B3LYP / 6-311 + G *水平的计算,可以获得有关反应的能量学和空间相互作用强度的其他信息。

nearly quantitative yields of /sup 1/O/sub2/. These two results are interpreted in terms of a diradical mechanism which leads to low yield of /sup 1/O/sub2/ and a concerted mechanism which leads to quantitative yields of /sup 1/O/sub2/, respectively. This interpretation is consistent with the observation of a magnetic fieldmore » effect on the yield of /sup 1/O/sub2/ from endoperoxides whose thermolyses
