As shown in Figure 4.1, there are additional reactive sites in phospholipids that potentially may be halogenated in the presence of peroxidase-derived hypohalous acids. In 1998, studies by Winterbourne et al. showed both hypochlorous acid and hypobromous acids react with both unsaturated aliphatic residues and the ethanol-amine of phosphatidylethanolamine (Carr et al. 1998). These studies showed that the amine was more reactive than alkenes and that the alkenes formed halohydrins only after the amine was consumed by the hypohalous acid. This was similar to the findings with plasmalogens which showed the chlorohydrins were only produced once the vinyl ether bond was consumed. Additionally these earlier studies demonstrated that bromoamine was reactive in producing bromohydrins, and this activity was greater than that observed with chloramines (Carr et al. 1998). Others have also shown the reactivity of hypohalous acids with ethanolamine (Jaskolla et al. 2009), but it is unclear whether these compounds are stable in cells or in vivo. 

Hypobromous acid (HOBr) and all three bromoamines species (NH2Br, NHBr2, NBra) are analyzed as a sum parameter and hypochlorous add (HCXZl), monochloramine (NH2CI), and chlorine dioxide (CIQ2) can be determined selectively. However, no distinction is possible between HOCl and the active bromine spedes. Free chlorine and NH2CI can be measured in the presence of ozone. The method is therefore suitable if combinations of disinfectants are used, such as chlorine/chlorine dioxide or chlorine/ ozone. In natural waters, the method provides a detection limit for all chlorine/bromine species of less than 0.1 mM. The oxidation reaction with ABTS is fast and has a known stoichiometry therefore, a direct calculation of the analyte concentration using the molar absorptivity of the colored oxidation produd is possible. 

The reduction of carboxylic acids by lithium in methylamine can be stopped at the imine stage the imines can be further reduced to secondary amines. Diamines are available from 2- or 3-bromoamines via the corresponding phosphoramides (Scheme 108) the flexibility of this route has been enhanced by the demonstrated potential of the intermediate / -aminophos-phoramides to undergo alkylation.
