摘要: 碘杂环类化合物的合成及性质已有报导[1—4],但碘杂环中碘作为正离子的1HNMR谱报导较少。由于碘正离子诱导效应的结果,使环上相邻质子的化学位移向低场移动,这主要是碘正离子吸引电子的结果,使相邻质子的电子云密度降低,化学位移向低场移动。本文报导了19个碘取代及碘杂环化合物的1HNMR谱,这种类型化合物的1HNMR谱未见过系统报导。

Abstract: This paper reports for the first time 1H NMRspectra of 19 kinds of iodinatcd compounds and iodonium heterocyciic compounda. In this paper, the Laciors affecting aromatic proton chemical shifts, such as the type of subsiitutnts, the solvent and nature of the counter ion arc discussed. Contribution of the iodonium substituent to the chemical shift increments of aromatic o-,m-,and p-protons is discussed, too.
