碘杂环类化合物的13CNMR谱研究
THE 13C NMR STUDIES ON HETEROCYCLIC COMPOUNDS CONTAINING IODINE
【摘要】 合成了一系列含不同杂原子的3 ,6 二硝基二苯并六元碘杂环类化合物,应用13C1HCOSY 谱对它们的13C NMR 谱峰进行了归属,讨论了杂原子及碘离子对谱峰的影响情况
【Abstract】 A series of 3,6 dinitrodibenzopyrioindium heterocyclic compounds with different heteroatoms were synthesized, and the chemical shifts of their aromatic carbons are assigned by \{\}\+\{13\}C \+1H COSY spectroscopy. The effect of different heteroatoms to the chemical shifts of the aromatic carbonatoms are discussed too. \;
