Abstract

The invention refers to heterogeneous ring compounds and, in particular, to reception Е-isomers of acrylic acid derivatives of the formula: where W is pyridinil-or pyridinil group substituted by halogen, С1-С4-alkil which, in turn, can be substituted by halogen, phenyl, С1-С4-alkoxyl, phenoxy group which can be substituted 1- methoxy carbonyl-2- methoxy ethylene, halogen, cyano-or nitro group, amino phormamido-, nitro, - cyano-or N-oxide group; or W - quinolinol -or Quinosolinil group, probably substituted by halogen and connected with A one of atoms of carbon of a ring: A-O or group S (O) n, where n=0 or 1, or 2, provided that when W - 5-trifluoromethyl pyridinil-2 then A is not oxygen. Technical result of the invention is reception of the compounds possessing higher herbicidal activity. Reception is conducted by elimination in corresponding acetal of methanol in acid or alkaline conditions. 6 tab.
