Khairullin, R. A. published the artcileReactions of diphenyl- and diethylphosphinodithioic acids with N-alkyl-2-haloaldimines in the synthesis of new P,S- and N,P,S-containing organic compounds, SDS of cas: 140-28-3, the publication is Russian Journal of General Chemistry (2017), 87(10), 2313-2319, database is CAplus.
Diphenyl- and diethylphosphinodithioic acids, unlike the stronger O,O-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
Russian Journal of General Chemistry published new progress about 140-28-3. 140-28-3 belongs to catalysis-chemistry, auxiliary class Benzenes, name is N1,N2-Dibenzylethane-1,2-diamine, and the molecular formula is C16H20N2, SDS of cas: 140-28-3.
