摘要
报道了７种新的α，α′－二氧代烯酮环二硫代缩醛化合物的ＮＭＲ谱。应用１Ｈ、１３ＣＮＭＲ谱等确定了这７种新化合物的分子结构．并对全部谱峰进行了归属．初步探讨了分子结构对化学位移的影响．
NMR spectra from 7 new kinds of α, α'-dioxoketene cyclic dithioacetals are reported in this paper. The structures were determined by 1H、13C NMR spectra etc., and the chemical shins of all NMR peaks have been assigned. The effects of structures on the chemical shifts are discussed.
