Hydrolysis of N-alkyl-2-dithiophosphatoaldiminium chlorides gives rise to new 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 aldiminium salts were obtained by the reaction of N-alkyl-2-chloroaldimines with O,O-dialkyl dithiophosphoric acids.
