Reduction oxygenation

Mico BA, Pohl LR. 1983. Reductive oxygenation of carbon tetrachloride trichloromethylperoxyl radical as a possible intermediate in the conversion of carbon tetrachloride to electrophilic chlorine. Arch Biochem Biophys 225 596-609. [Pg.156]

Results of a chemical activation induced by ultrasound have been reported by Nakamura et al. in the initiation of radical chain reactions with tin radicals [59]. When an aerated solution of R3SnH and an olefin is sonicated at low temperatures (0 to 10 °C), hydroxystannation of the double bond occurs and not the conventional hydrostannation achieved under silent conditions (Scheme 3.10). This point evidences the differences between radical sonochemistry and the classical free radical chemistry. The result was interpreted on the basis of the generation of tin and peroxy radicals in the region of hot cavities, which then undergo synthetic reactions in the bulk liquid phase. These findings also enable the sonochemical synthesis of alkyl hydroperoxides by aerobic reductive oxygenation of alkyl halides [60], and the aerobic catalytic conversion of alkyl halides into alcohols by trialkyltin halides [61]. [Pg.91]

Humphry Davy s process for the isolation of the alkali metals by the aid of the electric current is now regarded as the foundation of dry electrometallurgy, and justly so in spite of the fact that M. van Marum 4 had previously reduced several compounds by subjecting them to the electrical discharge. These methods were described in M. van Marum s pamphlet Experiences, qui font voir, qu il y a de la calorique dans la fluid ilectrique (Haarlem, 1795). He noted that in the reduction oxygen gas is evolved, and he credited the decomposition to the heating effect of the electric current. A few years later, J. W. Ritter decomposed silver salts by the discharge from a small electrical machine. [Pg.446]

Aminomercuration aminoalditols The synthesis of the natural aza-alditol 1-deoxynojirimycin (4) from methyl a-D-glucopyranoside involves the reductive ring-opening (Zn) and reductive amination (NaBH3CN) of 1 to give 2 in 91% yield. Aminomercuration of 2 results mainly in the bromomercurial 3, which was converted into the aza-sugar 4 by reductive oxygenation and deprotection. [Pg.175]

For instance, oxygen removes electrons from magnesium. Because it accepts those electrons, its oxidation number decreases from 0 to —2 (a reduction). Oxygen is therefore the oxidizing agent in this reaction. [Pg.129]

Cathodic protection also can be accomplished by lowering the electrode potential to E M, the equilibrium potential for the metal to be protected, by an external power source. The circuit used to accomplish this is the same as shown in Fig. 2.12. With slight modification, it is again shown in Fig. 4.25 in which the metal to be protected is iron and the cathodic reaction supporting corrosion is either hydrogen-ion reduction, oxygen reduction, or both. [Pg.172]
