METHOD OF SYNTHESIS OF DIISOBUTYLTETRATHIOPHOSPHORIC ACID DIETHYLARSINOUS ESTERS Russian patent published in 1999 - IPC

Abstract RU 2132333 C1

FIELD: chemistry of organophosphorus compounds. SUBSTANCE: invention relates to a method of synthesis of diisobutyltetrathiophosphoric acid diethylarsinous esters of the formula (I): (i-BuS)₂P(S)SAsEt₂ by reaction of tetraphosphordecasulfide with diethylthioarsinous acid isobutyl ester of the formula i-BuSAs-Et₂ at 20 C in the presence of benzene followed by isolation of the end product by the known procedures (distillation). Invention relates to the new method of synthesis of the new compound that can be used as a fungicide or an insecticide. EFFECT: improved method of the synthesis of the new compound. 1 ex
