It is one of the prototypical organic nitroso compounds. Nitrosation of neotame to nitroso compounds is hypothetical. Prototypes for such compounds are the organic nitroso compounds, such as nitrosobenzene. Like other nitroso compounds, it features a bent C-N=O linkage. Under simulated gastric conditions, nitrosothiols rather than nitrosamines are the main nitroso species being formed. Therefore, the nitroso group is less available to donate electrons. The nitroso intermediate (4) has been isolated from the reaction. The resultant nitroso compounds undergoes tautomerization to the isolated oxime product. They feature a nitroso group (NO) bonded to a deprotonated amine. Upon photolysis these compounds release the acyl nitroso species which then further decompose.
