Singlet Oxygen: a Reagent in Organic Synthesis
In the introduction, the generation, the electronic state and the reaction of singlet oxygen (102) with carbon—carbon double bonds is described. For preparative purposes, 102 is generated by dye-sensitized excitation of oxygen (02). The photo-oxygenation reaction leads to the formation of peroxides, which can be used as intermediates in the organic synthesis. Described are processes of preparat...
متن کاملReaction of Organic Sulfides with Singlet Oxygen. A Revised Mechanism
On the basis of ab initio calculations we propose a revised mechanism for the reaction of organic sulfides with singlet oxygen, which is more consistent with experimental evidence than previous schemes. In aprotic solvents the reagents initially form a weakly bound peroxysulfoxide, with a small barrier due to entropy. The peroxysulfoxide may decay back to ground state (triplet) oxygen, be trapp...
متن کاملSinglet Oxygen
Singlet oxygen (O2) is a higher energy state molecular oxygen species. It is one of the most active intermediates involved in chemical and biochemical reactions. To fully appreciate the reactivity of O2, it is necessary to understand its physical and chemical nature. This paper reviews the generation, quenching and detection of O2. Its properties, possible chemical reactions are presented as we...
متن کاملMicroenvironment-switchable singlet oxygen generation by axially-coordinated hydrophilic ruthenium phthalocyanine dendrimers.
A series of new metallodendrimers built around a ruthenium phthalocyanine core has been prepared. Employing a convergent synthetic strategy, pyridine-containing ligands were prepared and then assembled onto the ruthenium phthalocyanine through axial ligand coordination. The growing shell of oligoethylene glycol chains surrounding the lipophilic core allows solubilisation in water. Photophysical...
متن کاملPorous Organic Cages for Sulfur Hexafluoride Separation
A series of porous organic cages is examined for the selective adsorption of sulfur hexafluoride (SF6) over nitrogen. Despite lacking any metal sites, a porous cage, CC3, shows the highest SF6/N2 selectivity reported for any material at ambient temperature and pressure, which translates to real separations in a gas breakthrough column. The SF6 uptake of these materials is considerably higher th...
