Abstract: 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.

Key words: β-conjugated diketenes, 1H、13C NMR spectrum, Molecular structure
