Abstract: FIELD: chemical industry. SUBSTANCE: described is method of preparing alpha-methoxyiminocarboxylic acid methylamides of formula I: alpha- wherein y is C-organic radical. Method is carried out by Pinner reaction of acylcyanide of formula II: alpha- with alcohol followed by reaction of ester formed in Pinner reaction: of formula IV: with (a) hydroxylamine to obtain oxime of formula V: by methylation of oxime of formula VI: or (b) with co- methylhydroxylamine to obtain oxime ester of formula VI: followed by reaction of oxime of formula VI with methylamine, Pinner reaction uses alcohol of formula III: wherein R is OH and boiling temperature of said alcohol is higher than 75 C. EFFECT: simplified process and high yield of the desired product. 11 cl, 14 ex, 22 tbl

Abstract: Described is a method of preparing essentially pure .alpha.-bis-oxime isomers of the formula (Ia): R1O-N=CR2-CR3=N-OR4, in which the groups R1O- and R2 are in the cis configuration with respect to the N=C bond, from a mixture of the cis and trans isomers (Ia and Ib), the various groups being defined as follows: R1, R4 are hydrogen, or an organic carbon group; R2 is hydrogen, cyano, nitro, hydroxy, amino, halogen or an organic group which may be bound directly or via an oxygen, sulphur or nitrogen atom to the main chain; R3 is hydrogen, cyano, nitro, hydroxy, amino, halogen, alkyl, haloalkyl, alkoxy, haloa lkoxy, alkylthio, alkylamino, dialkylamino or cycloalkyl, Said method is characterized in that the mixture is treated in an organic solven t with a Lewis acid.
