在对咪唑类化合物的研究过程中,我们重新研究了1965.1中报道的1-甲基咪唑-甲碘化物(1)的核磁共振波谱。与以前的文献相比,我们现在发现,在C-4和C-5上的芳香族质子在较低的磁场(H-2,1,22ppm,S,布罗德;H-4,5,r2.47ppm,d,J=1.7HZ;在水中,dss=10)上比在1-甲基-碘上吸收更低。
In the course of our studies in imidazoles, we reinvestigated the nmr spectrum of 1-methylimida-zole methiodide (1), which hadbeen reported in 1965.1 In contrastto the earlier paper, we have now found that the aromatic protons at C-4 and C-5 absorb at a lower field (H-2, 1, 22 ppm, s, broad; H-4, 5, r 2.47 ppm, d, J= 1.7 Hz; in water, DSS= 10) than in 1-methyl-
