EtO < i-PrO ⪢ tert-BuO. On treatment with tetrabutylammonium fluoride in DMSO, dioxetanes (10e - 10h) bearing a m-siloxyphenyl decompose rapidly to emit intense blue light with ΦCL > 0.2. For the base-induced decomposition of 10e - 10h, the order of rate of decomposition is MeO < EtO < i-PrO < tert-BuO.
1-烷氧基-1-芳基-2,2-二异丙基乙烯(9)的低温单线态氧合以高选择性产生相应的1,2-二氧杂环丁烷(10)。二烷环烷(10)具有足够的热稳定性,可以在室温下处理,尽管烷氧基会显着影响其热稳定性,并且半衰期的顺序为MeO 0.2。对于碱诱导的10e-10h分解,分解速率的顺序为MeO
