designed to oxidize hydrophobic organic substrates with singletoxygen (1O2, 1Δg) generated from the disproportionation of hydrogenperoxidecatalyzed by molybdateions. The microemulsion was prepared by mixing methylene chloride, sodium dodecylsulfate, n-butanol, and aqueous molybdate. Flash photolysis studies have shown that in such media singletoxygen exhibits a similar kinetic behavior that under homogeneous
specific trapping have shown that CaO(2).2H(2)O(2) can be stored for several days at -80 degrees C and that the yield of (1)O(2) is equal to 25%. Oxidation of typical organic substrates in methanol or THF through [4 + 2] or [2 + 2] cycloaddition and ene reaction have been carried out on a preparative scale with total conversion and selectivity.
Going in for infra red: The development of phthalocyanine catalysts directly activated by NIR light to transform small organic molecules is described. The choice of solvent is important to promote cross-dehydrogenative coupling under irradiation with 810 nm NIR light. A combined experimental and computational mechanistic analysis revealed that this NIR reaction involves a singlet-oxygen-mediated mechanism
limiting oxidation can be a powerful tool for clarifying the role of oxidation in the transportproperties of crystalline rubrene, which is still unclear. Here, the synthesis of a series of substituted rubrene derivatives from dimerisation of propargyl alcohols is described together with the analysis of their stability to oxidation and electrochemical properties in solution.

In the dark and very fast: The generation of singlet oxygen (1O2) from endoperoxides, which are readily available by photooxygenation of the corresponding anthracenes, proceeds within minutes in the dark (see scheme), a rate hitherto unknown for other anthracenes or naphthalenes. This provides an efficient chemical source of singlet oxygen under very mildconditions.
在黑暗中并且非常快:在黑暗中,几分钟内即可从内过氧化物中产生单线态氧(1 O 2),这些光可通过相应的蒽的光氧化而容易地获得(见方案),这是其他蒽或其他蒽迄今所未知的速率萘。这在非常温和的条件下提供了有效的单重态氧化学来源。
