摘 要:三氟氯菊酸與光氣反應得到三氟氯菊酰氯,然后在水相曲拉通膠束中與醛醚和氰化鈉縮合得到三氟氯氰菊酯。最后經(jīng)差向異位生成最終產(chǎn)物高效三氟氯氰菊酯,總收率達71.4%(以三氟氯菊酸計),產(chǎn)品純度達99.0%。 |
關(guān)鍵詞:曲拉通;水相膠束;高效三氟氯氰菊酯 |

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 |
