Structure and Dynamic Behavior of Selected Carbanionic Species

这项研究将集中于一个全面的程序，以探索非溶剂化(RLi)n超聚集体的流动动力学，(RLi)n团簇中的Li自旋计数，离子对中离子-离子重定向的方式，Li内部溶剂化的立体化学导致的可变离域，结构的空间效应，共轭双阴离子盐，Li-C，C双键配位以及离子对在液晶介质中的化学和核磁共振性质。实验工作还将得到计算的补充。有了这一续期奖，有机动力学项目将支持俄亥俄州立大学化学系吉迪恩·A·弗拉恩克尔博士的研究。Fraenkel教授将专注于使用核磁共振技术确定有机锂化合物的溶液结构。这类化合物表现出的多才多艺和有用的合成化学使这一结构工作变得更加重要。

This research will focus on a comprehensive program which probes the fluxional dynamics of unsolvated (RLi)n hyperaggregates, Li spin counting in (RLi)n clusters, modes of ion-ion reorientation within ion pairs, variable delocalization resulting from stereochemistry of internal solvation of Li, steric effects of structure, conjugated dianion salts, Li-C,C double bond coordination and chemistry and Nuclear Magnetic Resonance (NMR) properties of ion pairs in liquid crystal medium. The experimental work will also be complemented by calculations. With this renewal award, the Organic Dynamics Program is supporting the research of Dr. Gideon A. Fraenkel of the Department of Chemistry at Ohio State University. Professor Fraenkel will focus his work on determining the solution structures of organolithium compounds using Nuclear Magnetic Resonance (NMR) techniques. The versatile and useful synthetic chemistry shown by this class of compounds makes this structural work even more important.
