9319062 Rosenberg Montana Dr. Edward Rosenberg, Chemistry Department, University of Montana, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program for research into the chemistry of trimetallia clusters. These studies will address fundamental questions relating to the types of molecular transformations which occur when more than one metal is involved in ligand activation. Specific topics to be investigated are: (1) the mechanism by which triosmium clusters promote low temperature transamination, (2) the regio-reactivity and reaction kinetics of a number of reactions of imidoyl complexes, (3) the aqueous coordination chemistry trimetallic clusters, and (4) the mechanism of metal-ligand hydrogen transfer reactions in polynuclear hydride complexes. Many important chemical processes are facilitated by the use of metal catalysts. In order to understand, and improve, such catalysts the ways in which chemical species interact with metals must be known. This project aims at determining the types of transformations which are possible when a small molecule interacts with two or more metal atoms. These will serve as models for the complex transformations which occur in a number of metal catalyzed reactions.

9319062 Rosenberg Montana蒙大拿大学化学系的Edward Rosenberg博士得到了无机、生物无机和有机化学计划的支持，研究三金属簇合物的化学。这些研究将解决有关的基本问题的类型的分子转化时发生的一种以上的金属参与配体活化。具体研究内容包括：（1）三锇原子簇促进低温转氨作用的机理;（2）三锇原子簇的区域反应性和反应动力学; （3）三金属簇合物的水溶液配位化学;（4）多核氢化物中金属-配体氢转移反应的机理。 许多重要的化学过程都是通过使用金属催化剂来促进的。为了理解和改进这种催化剂，必须知道化学物质与金属相互作用的方式。该项目旨在确定当小分子与两个或更多个金属原子相互作用时可能发生的转化类型。这些将作为模型的复杂的转变发生在一些金属催化反应。
