Hypochlorite as oxidant

This compound is a potent oxidant, however, and it readily attacks carbon-carbon double bonds.14 15 Procedures for in situ generation of RuC>4 from RuCF using periodate or hypochlorite as oxidants are available.16...

Diazirines 7 are usually produced by the Graham procedure (Scheme 6) <1965JA4396> or by the oxidation of N-unsubstituted diaziridines using silver oxide or tert-butyl hypochlorite as oxidants . For example, the unstable diaziridines 10, which can be generated from aldehydes 8 by a modified Schmitz reaction, are converted in situ to diazirines 9 by oxidation with / r/-butyl hypochlorite (Scheme 7) <2000TL795>. 

The Cfi primary alcohol group in carbohydrates can be oxidized selectively by the in situ generation of the nitrosonium ion 2 using hypochlorite as oxidant and the bromide/hypobromide co-catalyst in water [21, 22]. An analogous system was applied to monosaccharide [22]. Recently it has been reported that MTO also... 

When 1-aminocyclopropanecarboxylic acid and analogs 7 were treated with lithium hypochlorite as oxidizing agent only small amounts of ethene were formed. The main products of this reaction were 3-hydroxypropanenitrile (8, X = OH Y = CN) and 3-hydroxypropan-amides 8 (X = OH Y = CONHR). ... 

Mn" porphyrins may be electrochemically oxidized in non-aqueous media to yield Mn " cation radicals and dications as the probable products." The redox potentials depend on the nature of the solvent, counter ion present, of any axially-bound ligands as well as on the basicity of the porphyrin ring involved. Water-soluble Mn " porphyrins are oxidized by a range of oxidants in aqueous alkaline solution to the corresponding Mn porphyrins which appear to exist as fx-oxo dimers using hypochlorite as oxidant, a second oxidation step also occurs. In this case the product has been postulate to be a Mn 0x0 porphyrin. The Mn and Mn porphyrins show only limited stability in water and revert to the stable Mn" porphyrin upon standing in the dark for several... 

This method was also employed by Winkler in 1900 and Hunter in 1909, the latter using sodium hypochlorite as oxidant. 

The use of halogens and hypochlorites as oxidizing agents is complicated by the change in the nature of the oxidation as the conditions of temperature, acidity, and concentration vary. The halogens not only show considerable difference in the position of the various equilibria and the speed at which the equilibria are attained, but also in the maximal concentrations as expressed by the solubilities. 

The Montanari protocol, although widely applicable, suffers from several environmental and/or economic drawbacks. It is not waste-free, because at least 1 equiv. of NaCl is produced per molecule of alcohol oxidized and the use of hypochlorite as oxidant can also lead to the formation of chlorinated by-products. Other shortcomings are the use of 10 mol%... 

Z lost can be removed from the casings (spray canisters) after the lids have been cut off only by manual work, an extremely hazardous activity. Decontamination of the disassembled parts and of the tools used, like spoons and spatulas, is possible only by using the very effective German emulsion, which contains tetrachloroethylene as solvent and calcium hypochlorite as oxidant. The used decontaminant solutions constitute a further disposal problem, because they cannot be released into the waste water channel but must be burned, like liquid CW agents, in the incineration plant in Munster.
