Solvent-Ion Pair Chiral Recognition

这项研究的重点是确定手性溶剂对手性双阴离子的影响。锂-核磁共振将用于研究几种取代的环辛四烯二阴离子的R和S手性异构体的锂盐在各种手性溶剂中的溶液。核磁共振研究将表明离子缔合平衡被溶剂和双阴离子的手性扰动的程度。还将研究对偶手性对环辛四烯环系电子亲和力的影响。通过这项本科院校研究奖(RUI)，有机动力学项目正在支持伊利诺伊州立大学化学系谢丽尔·D·史蒂文森博士的研究努力。史蒂文森教授将专注于展示使用环八碳四烯基二阴离子可以实现的溶剂手性识别的程度。该地区为本科生和硕士研究生提供了一个很好的参与机会。

The focus of this research is to determine how chiral solvents will effect a chiral dianion. Lithium-NMR will be used to investigate solutions of the lithium salts of the R and S chiral isomers of several substituted cyclooctatetraene dianions in a variety of chiral solvents. The NMR studies will indicate the extent to which ion association equilibria are perturbed by the chirality of the solvent and the dianion. The effects of the dual chirality on the electron affinity of the cyclooctatetraene ring systems will also be studied. With this Research in Undergraduate Institutions (RUI) award, the Organic Dynamics Program is supporting the research efforts of Dr. Cheryl D. Stevenson of the Department of Chemistry at Illinois State University. Professor Stevenson will focus her work on demonstrating the extent of solvent chiral recognition that can be achieved with cyclooctatetraenyl dianions. The area provides an excellent opportunity for involvement of undergraduate and masters level students.
