Hydrolysis of the new types of iminiumsalts was used to synthesize О,О-dialkyl-S-(1,1-dimethyl-2-oxoethyl)dithiophosphates or 2-dialkoxythiophosphorylthio-substituted aldehydes with carbon isochain. Reactions of aldehydes with N-, N,N-, and O,N-nucleophiles gave new phosphorylated imines containing an acetal group at different positions, perhydro-1,3-diazol and oxazol with the diisopropoxythiophosphorylthio

O,O-DialkylS-(1,1-dimethyl-2-oxoethyl) dithiophosphates, 2-(dialkoxythiophosphorylthio)-substituted aldehydes with branched carbon groups, were obtained by hydrolysis of phosphoryl-containing iminium salts. The reaction with primary amines results in imines containing acetal group in different positions. Tri- and tetra-substituted perhydro-1,3-diazoles and oxazoles containing a phosphorus atom in

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

representatives of O,O-dialkyl dithiophosphato-substituted aldehydes, i.e., O,O-dialkyl S-(1,1-dimethyl-2-oxoethyl) dithiophosphates. Using reactions with trialkyl orthoformates, alkylamines, and substituted hydrazines, they were converted to the corresponding acetals, imines, and hydrazones. Their oxidation involves the aldehyde group to give a corresponding phosphoruscontaining carboxylic acid. The starting
