Abstract:The lambda cyhalthrin acid was synthesized from the adduct of methyl 3,3-dimethyl-4-pentenoate via a one-pot cyclization-saponification process in aqueous micelles. Then, the lambda cyhalthrin reacted with phosgene to afford the corresponding acyl chloride. The cyhalothrin was prepared through the condensation of the above acyl chloride, 3-phenoxy-benzaldehyde and sodium cyanide in Triton X100 aqueous micelles. Finally, the gamma-cyhalothrin was produced by an epimerization reaction. The purity of gamma-cyhalothrin was 99%, and the total yield was 54.2%. |
Key words:Triton X100; aqueous micelles; gamma-cyhalothrin |
