建议：9312012摘要日期：06/08/93 PI：里奇研究所：宾夕法尼亚州立大学将开发主族有机金属化合物的制备，并将阐明这些化合物的结构和反应。研究的一部分将针对合成有机金属阴离子和配位有机金属阳离子的新策略。该过程包括利用适当的配位剂将一种有机金属化合物转化为配位的有机金属阳离子，并且在该过程中，负基被转移到第二有机金属化合物以得到有机金属酸根离子。在这项工作的第二部分，将研究有机镁和有机锌物种与酮的反应机理。研究的第三部分将开发有机镁离子的新合成方法，并确定这些离子的结构特征。来自有机动力学项目的这笔赠款支持宾夕法尼亚州立大学赫尔曼·G·里奇教授的继续工作。将开发新的策略来合成金属有机化合物，其中金属离子(镁和锌)带有负电荷。有机金属物种的结构将通过X射线和光谱分析方法确定。这些有机金属化合物的反应将被研究，其中将特别注意新的合成应用。***

Proposal: 9312012 ABSTRACT Date: 06/08/93 PI: Richey Institution: Pennsylvania State University The preparation of main-group organometallic compounds will be developed, and the structures and reactions of these compounds will be elucidated. One portion of the research will be directed to new strategies for synthesizing organometallate anions and coordinated organometallic cations. The procedure involves the conversion of one organometallic compound, with a suitable coordinating agent, to a coordinated organometallic cation, and in the process, a negative group is transferred to a second organometallic compound to give an organometallate ion. In a second portion of the work, mechanisms of reactions of organomagnesiate and organozincate species with ketones will be studied. The third portion of the research will develop new synthetic procedures for organomagnesiate ions and determine structural features of these ions. %%% This grant from the Organic Dynamics Program supports the continuing work of Professor Herman G. Richey at Pennsylvania State University. New strategies will be developed for the synthesis of organometallic compounds where the metal ions (magnesium and zinc) carry a negative charge. The structures of the organometallic species will be determined by x-ray and spectroscopic methods. Reactions of these organometallic compounds will be investigated, where particular attention will be paid to new synthetic applications. ***
