A process for the preparation of Ester Cyano (6 - (FE - noxi replaced) - 2-pyridinyl acid 3 - (methyl) - 2,2 2,2 - carboxylic dimetilciclopropan haloetenil)

摘要

Process for producing Ester cyano - (6 - (substituted phenoxy) - 2 - dinil peri acid methyl) - 3 - (2,2 - dihaloetenil) - 2,2 - carboxylic dimetilciclopropan of formula (i), in which z is Fluorine, Chlorine or Bromine; X may be one of several types of radicals and N is 0 - 2.Involves the reaction of 6 - (substituted phenoxy) picolinaldehido with Halide acid 3 - (2,2 - dihaloetenil) - 2,2 - dimetilciclopropano carboxylic equimoleculares proportions in an Inert Solvent, in the presence of an alkali metal cyanide, such as SODIUM CYANIDE, and temperature. Re 30 and 100 C. these compounds have applications in agriculture as insecticides.
