In this project ("Structures and Reactions of New Main-Group Organometallic Compounds") funded by the Organic Dynamics Program of the Chemistry Division, Professor Herman G. Richey in the Chemistry Department at Pennsylvania State University will investigate the structures and reactions of new organometallic species of main-group elements. The study will also involve preparation of new organometallics and generating a new species of more reactive organomagnesium compounds. This project will be concerned with the preparation and study of species formed from organomagnesium compounds by additions of crown ethers or simple salts, such as alkali metal alkoxides and tetraalkylammonium halides. These new species, which include coordinated organomagnesium cations, threaded organomagnesium-crown ethers, and various organomagnesiate anions, are considerably more reactive than conventional organomagnesium compounds, and with some substrates afford different products. The scope and mechanisms of their reactions with ketones and other reactions will be studied. Similar investigations of organozincate anions formed from organozinc compounds and salts will also be performed.

美国宾夕法尼亚州立大学化学系教授赫尔曼·G·里奇在化学系有机动力学项目“新型主族有机金属化合物的结构和反应”中，将研究新型主族金属有机化合物的结构和反应。这项研究还将涉及制备新的有机金属化合物，并产生一种新的更具活性的有机镁化合物。该项目将涉及有机镁化合物通过添加冠醚或简单盐，如碱金属醇氧化物和四烷基卤化铵形成的物种的制备和研究。这些新物种包括配位的有机镁阳离子、螺纹状有机镁冠醚和各种有机镁阴离子，它们比传统的有机镁化合物活性高得多，并且与一些底物产生不同的产物。将研究它们与酮和其他反应的范围和机理。还将对由有机锌化合物和盐形成的有机锌阴离子进行类似的研究。
