制备方法与用途

化学性质

本品纯品为白色结晶固体,工业品则呈现浅黄褐色,熔点为141~142℃。它可溶于甲醇乙醇丙酮二氯乙烷乙酸乙酯

用途

5-氨基-3-氰基-1-(2,6-二氯-4-三氟甲基苯基)吡唑,简称吡唑,是杀虫剂氟虫腈的中间体。

生产方法

该化合物通过以2,6-二氯-4-三氟甲基苯胺为原料制备。首先,在反应瓶中加入硫酸和溶剂,并在搅拌下分批加入亚硝酸钠,搅拌30分钟后,在20~40℃滴加2,6-二氯-4-三氟甲基苯胺并继续搅拌1小时,得到该苯胺的重氮盐。然后,在该重氮盐中加入2,3-二氰基丙酸乙酯,室温下搅拌2小时。

将此混合物中的物料转移至分液漏斗中,先用层分离,并用二氯甲烷萃取,合并二氯甲烷相后,用洗至pH值为9。再移入反应瓶,加入氨水并继续在室温下搅拌2小时。之后进行分层操作,层再次用二氯甲烷萃取,合并后的二氯甲烷层再用洗涤至中性。最后,蒸去二氯甲烷后得到产品。

    Design, Synthesis and Insecticidal Activity of Novel Phenylpyrazoles Containing a 2,2,2-Trichloro-1-alkoxyethyl Moiety
    摘要:
    A series of novel phenylpyrazoles containing a 2,2,2-trichloro-1-alkoxyethyl moiety were designed and synthesized via the key intermediate 5-trichloroethyl-ideneimino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-alkylsulfenylpyrazole (5). The addition reaction of the imine 5 was closely related with the nature of the alcohol. The target compounds were confirmed by H-1 NMR and elemental analysis. The results of bioassays indicated that the target compounds possessed excellent activities against a broad spectrum of insects such as bean aphid (Aphis craccivora), mosquito (Culex pipiens pallens) and diamondback moth (Plutella xylostella). Especially, the foliar contact activity against bean aphid of compound 7h at 2.5 mg kg(-1) was 89%, the larvacidal activity against mosquito of compound 6c at 2.5 mu g kg(-1) was 100%, the activity against diamondback moth of compound 7a at 5 mg kg(-1) was 87%, and all of these activities were much higher than the contrast ethiprole. The results of insecticidal activities showed that the two pairs of enantiomers 7d-1 and 7d-2 gave activities without distinctive difference, and it was the similar situation for 7e-1 and 7e-2. Interestingly, the target compounds exhibited high selectivity between diamondback moth and oriental armyworm, both of which are of the order Lepidoptera. The 2,2,2-trichloro-1-alkoxyethyl moiety was essential for high insecticidal activities.
