新型萘酚类二当量青成色剂2－CC的核磁共振研究

本文通过多种去耦方法及二维核磁共振技术（包括反转门控去耦、非畸变极性转移增强技术、二维１３Ｃ—１Ｈ相关谱、二维１Ｈ—１Ｈ相关谱、二维Ｊ分解谱）研究了新型萘酚类二当量青成色剂１－羟基－４－（甲磺酰基乙氧基）－Ｎ－正十六烷基－２－萘甲酰胺（２－ＣＣ）分子中１３Ｃ—１Ｈ间的耦合作用．在此基础，归属了２－ＣＣ分子中碳和氢原子的化学位移信号；并且进一步讨论了分子中氢键和虚假远程耦合作用

Studies on Nuclear Magnetic Resonance of a Novel 2 Equivalent Naphthol Cyan Coupler 2 CC

The coupling actions between carbon and hydrogen in 1-hydroxy 4 (2 methylsulfonylethoxy) N n hexadecyl 2 naphthamide (2 CC) as a novel 2 equivalent cyan coupler were discribed by using various 2D NMR techniques and decoupling methods (including lnverse Gate Decoupling; Distortionless Enhancement by Polarization Transfer; 2D 13 C- 1H COSY; 2D 1H- 1H COSY and 2D J-Resolved Spectroscopy). On the basic, all the Chemical shifts of carbon and Hydrogen in the 2 CC were completely assigned, and H-bond and virtural long-range coupling of the 2 CC were further discussed.
