“…Three different reaction paths could be suggested for the P−C bond cleavage of DMABP in acidic conditions (Schemes −4). All of them were suggested before using the available experimental evidence. ,, The first mechanism (Scheme ) is the decomposition of the P−C bond due to the protonation of oxygen. While the second probable mechanism (Scheme ) involves hydrogen transfer from protonated anilino-nitrogen to the phosphorus atom, the third one (Scheme ) assumes the cleavage of the neutral molecule into cations.…”

“…The analysis of concentrations of components in solution indicates that at least a large part of phosphonic acid originates from the direct decomposition of diester. Additionally, as indicated by Deron et al the initiation of the reaction takes place through the protonation of oxygen of the phosphonic group. The amino group of the aniline part is a competitive site for such a protonation, and experimental studies indicated a correlation between the acidity of amino group and the kinetics of the reaction .…”
