ABSTRACT:
Reaction of amine-containing substrates with hydrogen peroxide can suffer from the problems of in situ generation of nitrosamines, which are allegedly carcinogens, as impurities and impaired product formation, especially in the presence of transition metals.
The problems can be ameliorated by employing a selected range of alkyleneaminopoly(methylenephosphonic acid) compounds such as cyclohexane-1,2-diaminotetra(methylenephosphonic acid).
