摘要: 由异戊烯醇-原乙酸三乙(甲)酯法相继合成了拟除虫菊酯类农药中间体3,3-二甲基-4-戊烯酸乙(甲)酯,4,6,6,6-四氯-3,3-二甲基己酸乙(甲)酯和2,2-二甲基-3-(2,2-二氯乙烯基)环丙烷羧酸乙(甲)酯等化合物,对这些化合物进行了元素分析、红外光谱、1H NMR等测定,与文献结果相符,为了进一步明确结构,测定了未见报道的13C NMR,给出了波谱数据归属.

关键词: 拟除虫菊酯类农药中间体, 13C NMR

Abstract: Intermediates of pyrethroid pesticides-ethyl (or methyl). 3,3-dimethyl-4-pentenoate. ethyl (or methyl). 4, 6, 6, 6-tetrachloro-3, 3-dimethyl hexanoate and ethyl. (or methyl) 2,2-dimethyl-3-(2,2-dichloroethenyl) cyclopanecarboxylate were synthesized in succession through prenol-orthoacetate method. Their elemental analysis. IR spectrum and 1H NMR were consistent with those reported. In order'to make clear the structures of these compounds further, the 13C and 1H NMR chemical shifts were assigned completely by H-H COSY and 13C-1H COSY spectra.

Key words: Intermediates of pyrethroid pesticides, 13C NMR
