A reaction between O,O-dialkyldithiophosphoric acids and N-alkyl-2-chloro-2-methyl-propanimines proceeds in two steps: a protonation of the imine group and a substitution of the chlorine atom, that leads to (dialkoxythiophosphoryl)sulfanyl-containing iminium salts.

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 iminiumsalts, namely, N-alkyl-2-(di phenyl thiophosphinylthio)-2-methylpropaniminium chlorides. These salts were used as the starting material to synthesize

only by a single pathway, specifically, reducing the cation of the primary iminium salt on the C–Br bond. New iminium salts were synthesized and converted into the corresponding aldehydes and imines. The aldehydes synthesized were converted into acetals and five-membered heterocyclic compounds.

that the structure of final products is dependent on the halogennature. To reveal the effect of the nature of substituents at P(IV) and N(III) on the structure of resulting products and the synthesis of polyfunctional OPCs of new types, we have studied the reactions of dimethyl, diethyl, diisopropyl, dinbutyl�, and di�2�chloroet� hyl phosphites (I) with (2�chloropropylidene)alkyl� amines ( II) containing
