Reactions of diphenyldithiophosphinic acid with N-alkyl-2-chloro-2-methylpropanimines
- Kazan National Research Technological University (Russian Federation)
In contrast to O,O-dialkyldithiophosphoric acids, the reactions of more weak diphenyldithiophosphinic acid with N-alkyl-2-chloro-2-methylpropanimines at a 1 : 1 reagent ratio follow two pathways. The first route is nucleophilic substitution of the chlorine atom of the initially formed iminium salt with the diphenylthiophosphinylthio moiety and the second route is the reduction of the C–Cl bond of this iminium salt cation. The main reaction direction is nucleophilic substitution producing new iminium salts, namely, N-alkyl-2-(di phenyl thiophosphinylthio)-2-methylpropaniminium chlorides. These salts were used as the starting material to synthesize new organophosphorus compounds bearing aldehyde, imine, and acetal groups and 1,3-diazolidine cycle.
