α,α′-二氧代烯酮环二硫代缩酮的NMR研究

NMR STUDY OF NEW α,α′ DIOXOKETENE CYCLIC DITHIOACETALS

报道标题化合物的ＮＭＲ谱，利用１Ｈ，１３ＣＮＭＲ和ＤＥＰＴ等技术确定新化合物的化学结构。

NMR spectra of the title compounds are reported in this paper. The new law of NMR spectrum were discovered for α,α′ dioxoketene cyclic dithioacetals. Their structures were determined by 1H, 13 C NMR spectra etc., and all 1H and 13 C NMR chemical shifts of the compounds have been assigned.
