摘要:

测定了戊环唑(1)、甲环唑(2)、丙环唑(3)的NMR谱,对其一般特征进行 了对比与讨论,用13C-1H COSY、13C-1H COLOC、DQF-COSY、DEPT等技术对它们的1H、13C NMR谱峰进行了全归属,并应用1H-1H NOESY谱研究其立体结构.

Abstract:

The 1H and 13C NMR chemical shifts of the title compounds 13 were assigned  in this article by using 1D and 2D techniques, including 1H, 13C , DEPT, 1H-1H DQF-COSY, 13C-1H COSY, COLOC and 1H-1H NOESY spectra. Alkyl groups show considerab le effects on 1H chemical shifts of the benzene and 13C chemical  shifts of the d ioxolane. The shift parameters of methyl and propyl substituent effects on the 13C chemical shifts of dioxolane are as follows: 8.12(α), 5.7(β), -1.1(γ)a nd 11.57(α), 4.77(β), 0.17(γ), respectively. The stereo-structures of  the synthetic compound 2 and 3, which are widely used in agriculture as a  kind of pow erful pesticides and fungicides, were elucidated by 1H-1H NOESY exp eriments.

Key words: 1-[2-(2,4-dichlorophenyl)-4-alkyl-1,3-dioxolan-2-yl-methyl]-1H-1,2,4-Triazole,  1H NMR,  13C NMR
