Dr. John Arnold, Chemistry Department, University of California - Berkeley, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division for the development of new monoanionic ligands. The chemistry of early transition metal and lanthanide complexes of the ligands will be explored. The major thrust is a new series of monoanion ligands that will be capable of supporting chemistry related to that presently dominated by Cp based systems. Specifically new functionalized 14-membered tetraazamacrocycles will be developed, their complexes with di and trivalent metals prepared, and their stoichiometric and catalytic reactivity investigated.Reactions mediated by transition metal and lanthanide element compounds are important on an industrial scale and provide ever increasing fundamental knowledge regarding the nature of the chemical bond. In recent years, there has been considerable effort in developing ligands that will tailor the chemical reactivity and properties of the metal. In this study new ligands will be designed to facilitate reactions at metal ions with a 2+ and 3+ charge. This is an important goal since many important processes that are known to take place at 4+ ions have not yet been efficiently developed for 2+ and 3+ counterparts. An important goal of the project is the education of young scientists at the graduate and postdoctoral level.

加州-伯克利大学化学系的John Arnold博士得到化学系无机、生物无机和有机化学项目的支持，开发新的单阴离子配体。将探索配体的前过渡金属和镧系元素配合物的化学。主要的推力是一个新的一系列的单阴离子配体，将能够支持化学相关的，目前占主导地位的Cp为基础的系统。具体地说，新的功能化的14元四氮杂大环将开发，其配合物与二和三价金属制备，和它们的化学计量和催化reactivityinvestigated.Reactions介导的过渡金属和镧系元素化合物是重要的工业规模，并提供越来越多的基础知识的性质的化学键。近年来，在开发将定制金属的化学反应性和性质的配体方面已经做出了相当大的努力。在这项研究中，新的配体将被设计为促进与2+和3+电荷的金属离子的反应。这是一个重要的目标，因为许多已知在4+离子发生的重要过程尚未有效地开发用于2+和3+对应物。该项目的一个重要目标是在研究生和博士后一级教育青年科学家。
