Process for the preparation of
trans-3-(z-2-chloro-2-aryl-vinyl)-2,2-dimethyl-cyclopropane-1-carboxylic
acid derivatives, and the use of intermediate products in agents for
compating pests
摘要:
The invention relates to a process for preparing trans-3-(Z-2-chloro-2-(4-aryl)-vinyl)-2,2-dimethyl-cyclopropane-1-carboxylic acid derivatives of Formula (I) from corresponding dehalogenated compounds of Formula (II) by dehalogenation. The invention also includes to the novel compounds of Formula (III) and a halogenation process for their production. The compounds of the invention are useful as intermediates and/or insecticides or acaricides.
