摘要/Abstract

摘要：

环氟菌胺是一种具有新型母核结构的优秀杀菌剂.该文采用¹H NMR、¹³C NMR、¹⁹F NMR、¹H-¹³C HSQC、¹H-¹³C HMBC和¹H-¹⁵N HMBC等多种核磁共振(NMR)技术,并结合质谱(MS)、紫外光谱(UV)和红外光谱(IR)等方法对环氟菌胺进行了解析,同时对一维核磁共振(1D NMR)波谱数据进行全归属,讨论了UV和IR的吸收峰与该化合物各官能团的对应关系、¹⁹F对其¹H和¹³C NMR谱峰的影响,以及MS主要离子碎片的归属和化合物裂解规律.

关键词: 液体核磁共振(Liquid-state NMR), 归属, 环氟菌胺, 质谱(MS)

Abstract:

Cyflufenamid is an excellent fungicide with novel molecular structure. In this paper, one-dimensional and two-dimensional NMR spectroscopy, combined with mass spectrometry (MS), ultraviolet spectroscopy (UV) and infrared spectroscopy (IR), were used to elucidate the structure of cyflufenamid. NMR chemical shifts of the compound were assigned. The correspondences between the UV/IR absorption peaks and the functional groups in this compoundwere discussed. The effects of the fluorine atoms in the compound on the ¹H and ¹³C NMR chemical shifts were investigated, as well as the possible fragmentation patterns of the compound.

Key words: Liquid-state NMR, assignment, cyflufenamid, mass spectroscopy
