摘　　要：报道了5种新的α，α′-二氧代烯酮环二氮代缩醛化合物的NMR谱，初步探讨了分子结构对化学位移的影响．NMR spectra of 5 new kinds of α,α′ - dioxoketene cyclic N, N-acetals are reported in this paper. The structures. were determined by 1H, 13C NMR spectra etc., and the chemical shifts of all NMR peaks kaye been assigned. The effects of structure on the chemical shifts are discussed.

关 键 词：共轭二酮 二氧代烯酮 环二氮代缩醛 NMR谱
