FIELD: organic chemistry, chemical technology. SUBSTANCE: product: derivatives of O-benzyloxime esters of the general formula (I)where: Y means hydrogen, C-C-alkyl, C-C-alkoxy, OH, CN, NO, Si(CH), CFor halogen; Z means the group: a)or b); Rmeans hydrogen, C-C-alkyl, C-C-alkenyl, C-C-alkynyl, C-C-cycloalkyl, unsubstituted phenyl or in the most of cases is substituted with trihalide, C-C-alkyl, C-C-alkoxy, C-C-alkoxy, C-C-alkylthio, or unsubstituted benzyl or in the most of cases is trisubstituted by similarly in aromatic ring; or cyclopropylmethyl, C-C-halogenalkyl, C-C-alkoxyalkyl; cyanomethyl, CO-R,, OH, NH,, C-C-alkylamine, or C-C-alkoxycarbonyl-C-C-alkyl; X means oxygen, sulfur or NR; Rmeans hydrogen, C-C-alkyl, C-C-alkenyl, C-C-alkynyl, C-C-cycloalkyl, C(O)R, OH, C-C-alkoxy, NHor C-C-alkylamine; Rmeans hydrogen, C-C-alkyl, C-C-alkenyl or C-C-alkynyl; Rmeans hydrogen, C-C-alkyl, C-C-halogenalkyl, C-C-alkoxy, C-C-cycloalkyl, C-C-alkoxycarbonyl or unsubstituted phenyl or mainly trisubstituted phenyl; Rand Rmean independently hydrogen, cyano, C-C-alkyl, halogeno-C-C-alkyl, C-C-alkenyl, C-C-alkynyl, C-C-cycloalkyl, cyclopropylmethyl, C-C-alkoxy, C-C-alkoxyalkyl, C-C-alkoxycarbonyl, C-C-alkylthio, C-C-alkylthioalkyl. Ring can be multimembered and has 15 carbon atoms (not above), unsubstituted but preferably trisubstituted and it has 0-3 heteroatoms of N, O or S and, except for, this ring can be joined by aliphatic bridge containing 4 carbon atoms (not above), and/or by CO, oxygen or sulfur, or Rand Rtogether with common carbon atom mean ring or multimembered ring system containing 15 carbon atom in rings (not above) that can be unsubstituted and, mainly, trisubstituted and has 0-3 heteroatoms of nitrogen, oxygen or sulfur. Invention relates to also synthesis of these derivatives and pesticide compositions for struggle against plant damage and for prevention of plant damage with microorganisms. EFFECT: improved method of synthesis. |
