Diphenyl- and diethylphosphinodithioic acids, unlike the stronger О,О-dialkyl phosphorodithioic acids, react with N-alkyl-2-chloroaldimines at a 1: 1 ratio, following two pathways: nucleophilic substitution of chlorine in the primary salt by the phosphinothioylthio group and reduction of the cation of the primary salt on the C–Cl bond. Nucleophilic substitution contributes more in the case of the stronger diphenylphosphinodithioic acid, as well as in the case of a large excess of the starting chlorimine. N-Alkyl-2-bromoaldimines react 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.

Bis(diorganylthiophosphinoyl)-disulfides were studied as sulfenylation reagents in the presence of CCl4, which gives rise to a more efficient utilization of disulfides.Five new ethers of diorganyldithiophosphinic acids are described and have been characte
