PROCEDURE

实验过程

Surprisingly, the applicants have also found it is possible to make gamma-cyhalothrin in a process wherein steps b) and c) can be combined (in a one-pot process), that is a process for the preparation of gamma-cyhalothrin in which 1R cis-Z 3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cyclopropanecarboxylic acid chloride (III) is reacted with 3-phenoxy benzaldehyde (IV) and a source of cyanide to give gamma-cyhalothrin (I).
