METHOD OF SYNTHESIS OF OXIME ESTERS BY INTERACTION OF OXAMINE WITH DIALKYLCARBONATES Russian patent published in 2001 - IPC

Abstract RU 2167149 C2

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method of synthesis of oxime esters of the general formula (Ia) where R³ is methyl; R⁴ is -C₁-C₆-alkyl; A is CH₃, -O-aryl, -Ch₂-O-aryl; X is oxygen atom. Oxime of the formula (IIa) where substituents have similar values are converted to salt using the base in the presence if necessary of organic solvent and then this salt is subjected for interaction with dimethylcarbonate. EFFECT: quantitative yield of end products, high selectivity of method. 12 cl, 1 tbl, 1 ex
