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 to support catalytic and stoichiometric reactions. The major thrust is to prepare 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 amidines and derivatized 1,4,7-triazacyclononanes will be developed, their complexes with 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 (groups that are attached to a metal) 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 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 3+ counterparts.

加州大学伯克利分校化学系的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以支持催化和化学计量反应。主要的推力是准备一个新的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。特别是新的功能化脒和衍生的1，4，7-三氮杂环壬烷将开发，它们与三价金属的配合物制备，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本知识的性质的化学键。近年来，人们在开发配体（连接到金属上的基团）方面做出了相当大的努力，这些配体将定制金属的化学反应性和性质。在这项研究中，新的配体将被设计为促进与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+离子处发生的重要过程尚未有效地开发用于3+对应物。
