在没有5的情况下，环氧化物的产生也受到了抑制。结果表明，在5存在下，二氧杂环己烷3在光氧化条件下是稳定的。自由基抑制剂2，6-二叔丁基对甲酚在4×1ct4M对5和1的共氧化没有显著影响。此外，4.2×1ct2 MDABCO完全抑制该反应。对照实验表明，在没有5的情况下，5对‘02基本上是惰性的
epoxide production in the absence of 5 hasalso been suppressed. We have shown that dioxetane 3 is stable under the photooxygenation conditions in the presence of 5. A free-radical inhibitor, 2, 6-di-ierf-butyl-p-cresol, at 4 X1ct4 M has no significant effect on the cooxidation of 5 and 1. Further, 4.2 X1ct2 M Dabco, a* 02 quencher, totally inhibits the reaction. Control experiments showed that 5 is essentially inert toward ‘02 in the absence of
