我们希望报道全氘代环辛烷-顺式-1,2-反式-1,2-高(II)和-1,1-高(III)的质子NMR谱。这些结果对环辛烷的构象有重要的影响,这是一个当前感兴趣的课题。2在钯炭存在下,在140 ℃下用氘氧化物重复交换环辛烯,得到环辛烯-?i4(> 99%D)(IV)。用二酰亚胺3还原IV得到I。水螅-
We wish to report the proton nmr spectra of perdeuteriocyclooctane-czs-1, 2-/z2 (I),-trans-l, 2-hi (II), and-1, 1-hi (III). The results have an important bearing on the conformation (s) of cyclooctane, a subject of current interest. 2 Repeated exchanges of cyclooc-tene with deuteriumoxide at 140 in the presence of palladium-charcoal yielded cyclooctene-¿? i4 (> 99% D)(IV). Diimide3 reduction of IV gave I. Hydrobora-
