METHOD OF SYNTHESIS OF ARSENIC β-CHLOROVINYLALKOXIDES Russian patent published in 1994 - IPC

Abstract RU 2017747 C1

FIELD: chemistry of arsenic-containing compounds. SUBSTANCE: method involves synthesis of compounds of the general formula ClCH=CHAs(OR2), where R-CH3, C2H5, iso-С3H7, n-C4H9, n-С4Н9, iso-С4H5, n-, n-C5H11, iso-C5H14. Process conditions: interaction of chlorovinyldichloroarsine with C1-C6-aliphatic alcohol at molar ratio 1:(3-8) in the presence of ammonia at pH 7.5-8 following by isolation of the end products by filtration and distillation. Yield is 93-94.5%. EFFECT: enhanced yield of the end products. 1 tbl
