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).
含胺底物与过氧化氢的反应会产生亚硝胺(据称是致癌物质)作为杂质原位生成和产物形成受阻的问题,特别是在过渡金属存在的情况下。
通过使用选定范围的亚烷基氨基多(亚甲基膦酸)化合物,如环己烷-1,2-二氨基四(亚甲基膦酸),可以改善这些问题。
