Reaction of O,O-dialkyldithiophosphoric acids with N-alkyl-2-haloaldimines
摘要:
Synthetic results of reactions of O,O-dialkyldithiophosphoric acids with N-alkyl-2-haloaldimines fundamentally depend on the nature of the halogen: in the case of Cl-substituted imines the reaction afforded 2-(dialkoxythiophosphorylthio)iminium chlorides, with bromoimines bis(dialkoxythiophosphoryl) disulfide and unsubstituted iminium bromide were obtained. According to dynamic P-31 NMR spectroscopy data the reason for this difference is the presence or absence of a free acid in the reaction medium.
Reactions of O,O-dialkyldithiophosphoric acids with N-tert-butyl-2-bromo-2-methylpropanimine and its salts
摘要:
The reactions of O,O-dialkyldithiophosphoric acids with N-tert-butyl-2-bromo-2-methylpropanimine and its salts resulted in reduction of the carbon-bromine bond in the iminium salt giving bis(dialkoxythiophosphoryl)disulfide and N-tert-butyl-2-methylpropaniminium bromide. This represents the first example of C-Br bond reduction by O,O-dialkyldithiophosphoric acids. (C) 2015 Elsevier Ltd. All rights reserved.

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.

Reaction of N-tert-butyl-2-chloro-2-methylpropanimine with thiocarboxylicacids has proceeded by two routes, one involving nucleophilic substitution of the chlorine atom in the primary iminium salt by acylthio group, and another via reduction of its cation at the C–Cl bond. Thiocarboxylicacids have reacted with 2-bromoaldimines only via reduction of primary salt cation at the C–Br bond. Acylthio-substituted

nucleophilic substitution of chlorine in the primary iminium salt by acylmercapto group and reduction of the C–Cl bond in the iminium cation. The reactions of thiolcarboxylic acids reaction with 2-bromoaldimine take exclusively the second pathway, specifically reduction of the C–Br bond in the cation of the primary iminium salt. Acylmercapro-substituted iminiumsalts and aldehydes and their acetals are synthesized
