研究了2-吡啶基取代基对碘代芳烃在碘化学中催化性能的影响。通过X-射线分析确定并证实了吡啶氮和亲电碘（III）中心之间的有效刘易斯碱加合物。这种排列显示出产生用于烯烃的催化双氧化的动力学上胜任的上级催化剂结构。它介绍了刘易斯碱加合物形成的概念作为碘（I/III）催化的动力学因素。
The influence of a 2-pyridinyl substituent on the catalytic performance of aryl iodides as catalyst in iodine(III) chemistry was explored. An efficient Lewis base adduct between the pyridine nitrogen and the electrophilic iodine(III) center was identified and confirmed by X-ray analysis. This arrangement was shown to generate a kinetically competent superior catalyst structure for the catalytic dioxygenation of alkenes. It introduces the concept of Lewis base adduct formation as a kinetic factor in iodine(I/III) catalysis.
