  摘要：

  在四苯基卟啉催化剂存在下，将(E)-2-甲基-2-丁烯酸衍生物（虎尾草酸衍生物）在四氯化碳中进行光氧化反应，通常可以高产率地得到3-羟基过氧-2-亚甲基丁酸衍生物。通过酸催化的环脱水反应，所获得的3-羟基过氧-2-亚甲基丁酸容易生成5-甲基-4-亚甲基-3-氧代-1,2-二氧杂环戊烷（一种过氧内酯），产率为61%。类似地，通过将(E)-2-甲基-2-丁烯醛就地氧化生成的3-羟基过氧-2-亚甲基丁醛进行环脱水反应，则生成3-羟基-5-甲基-4-亚甲基-1,2-二氧杂环戊烷。

  corresponding methyl esters using singlet oxygen were investigated in methanol and methanol/water solvent mixtures and compared to non-hydrogen-bonding solvents with different dielectric constants. The major and minor ene allylic hydroperoxide products were quantified and this ratio for the acids was found to be dependent on a hydrogen-bonding interaction between the solvent and substrate.

  interior of the zeolite was documented. The nearly identical reaction rates in the two slurry solvents are attributed to a leveling of the singlet oxygen lifetime by the zeolite framework. A consideration of the rates of the various intrazeolite processes was used to estimate an upper limit for the intrazeolite lifetime of singlet oxygen.

  Creating a stationary fluorinated environment inside the zeolite cavity can increase the reactivity observed for intrazeolite photooxidation of alkenes. Exchanging the zeolite with fluorinated organic cations is a much more effective strategy than simply using a fluorinated solvent for slurry irradiations. Use of cations containing C-F bonds is also more efficient than use of deuterated cations for creation of a singlet oxygen friendly environment where the quenching processes are slowed down. Doping the zeolite with fluoro-organic cation 4 resulted in an increase in the singlet oxygen lifetime to 12 mu s.
