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 کاملA Mems Singlet Oxygen Generator
The design, creation, and demonstration of a singlet oxygen generator (SOG) that operates on the microscale are presented. The micro singlet oxygen generator (μSOG) chip creates singlet delta oxygen (O2(Δ)) in an array of packed bed reaction channels fed by inlets with pressure drop channels to equalize flow. An integrated capillary array separates the liquid and gas byproducts, and microscale ...
