Usage

General Description

Tetraethyl thioperoxydiphosphate, also known as Tetraethyl pyrophosphate (TEPP), is a highly toxic organophosphate compound that is commonly used as an insecticide and acaricide. It acts by inhibiting the activity of cholinesterase enzymes, resulting in the accumulation of acetylcholine in the nervous system and leading to paralysis and death of the target pests. TEPP is classified as a restricted use pesticide due to its high acute toxicity to humans and potential environmental hazards. Exposure to TEPP can cause symptoms such as nausea, dizziness, headaches, muscle twitching, and difficulty breathing. Due to its extreme toxicity, strict safety precautions and protective measures are necessary when handling and using this chemical.

Reaction of O,O-dialkyldithiophosphoric acid with N-tert-butyl-2,2-dihalopropanimines

O,O-Dialkyldithiophosphoric acid reacted with N-tert-butyl-2,2-dihalopropanimines to give iminium salt as a primary product, which further sequentially undergoes reaction with two equivalents of dithiophosphoric acid to initially reduce the C—X (X = Cl, Br) bond in the iminium salt and then nucleophilic replacement of the halogen atom with dialkoxydithiophosphate group. The final reaction products are the reduction—substitution product of the primary salt and bis(dialkoxythiophosphoryl) disulfide.

Reactions of O,O-dialkyldithiophosphoric acids with N-tert-butyl-2-bromo-2-methylpropanimine and its salts

Abstract 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.
