Hypochloride

The method of choice for preparing thietane oxides is the oxidation of thietanes. This can be conducted using hydrogen peroxide, sodium hypochloride -, sodium metaperiodate , NaI04 and m-chloroperbenzoic acid . 

Fragments of C. foliacea thalli were stored dry. Before use, these were abundantly rinsed in tap water and rapidly surface sterilized (10 seconds) in 1% sodium hypochloride. They were then inoculated in the in ratio of 0.5 g Cladonia thallus to each Petri dish containing 20 ml medium (water or Mohr) with 200 pi spore suspension (see above) or 20 shoot fragments. 

Organotellurium compounds are readily oxidized from the divalent to tetravalent state. Consequently, this property makes tellurides attractive as scavengers of reactive oxidizing agents such as hydrogen peroxide, hypochloride and peroxyl radicals. 

Different immobilization methods were applied for Jacobsen s catalyst. The entrapment of the organometallic complex in the supercages of the dealuminated zeolite was achieved without noticeable loss of activity and selectivity. The immobilized catalysts were reusable and did not leach. For the oxidation of (-)-a-pinene the system used only O2 at RT instead of sodium hypochloride at 0 °C. There was a disadvantage in the use of pivalic aldehyde for oxygen transformation via the corresponding peracid. This results in the formation of pivalic acid, which has to be separated from the reaction mixture. 

The benzodiazepine (236) can be chlorinated at the 1-position using sodium hypochloride or t-butyl hypochlorite, or at the 3-position using NCS. The 3-chloro derivative can also be prepared by treatment of the 3-hydroxy compound with thionyl chloride. Halogens at the 3-position can be displaced to give 3-amino derivatives. 

There are some known unsuccessful attempts to carry out alkylation (Mel, Me2S04), halogenation (tert-butyl hypochloride) and nitration of aromatic dihydrobenzodiazepines [7, 105]. Such attempts only resulted in the destruction of the seven-membered heterocycle. As a rule, these destructive processes are typical of dihydrodiazepine systems and often manifest themselves during the synthesis and study of these compounds. Therefore, the results of the destruction of a seven-membered heterocycle are most widespread and include its decomposition into ortho-diamine and carbonyl compounds (Scheme 4.43, reactions A and B) [105, 106] and benzimidazole rearrangement accompanied by splitting out of a methyl aryl ketone molecule (Scheme 4.43, reaction C) [117]. 

The ring opening of rfr-azetidin-2-ones 323 with 2,2,6,6-tetramethylpiperidinyl-l-oxy (TEMPO) and sodium hypochloride furnished the ring expansion product isoxazolidinc-2,5-dionc 324, which is used in the synthesis of the macrocyclic antibiotic lysobactin (Equation 112) <2000PAC1763>. 

Chlorhexidine is available in the form of acetate, gluconate, or hydrochloride. Chlorhexidine salts are incompatible with soaps and other anionic materials. Fabrics in contact with chlorhexidine solution may develop brown stains if bleached with hypochloride.

Warning Certain pesticides are oxidizers, such as calcium hypochloride (a common sanitizer), and some herbicides and desiccants contain chlorites, which should not be contained with sawdust or other combustible material. These absorbent materials can combined with the oxidizer to create a fire hazard and could burst into flame.

Work with the toxin should be performed in a contained space and all the materials contaminated with CNTs should be autoclaved or washed at the end of the experiment with dilute sodium hypochloride, due to the extreme sensitivity to oxidants of CNTs (see Chapter 20).
