Dr. Kenneth G. Caulton, Chemistry Department, Indiana University, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program of the Chemistry Divison to utilize the [(R2PCH2SiMe2)2N]-1 (PNP) ligand to develop atom transfer reactions to and from metals coordinated to it. Work proposed includes transfer of atoms to highly reduced (PNP)M or from rare examples of (PNP)MG where G may be O or N. Properties of the complexes, such as spin state, bond order, chemical bond-type and location of empty orbitals and of lone pairs, will be studied for their influence on chemical reactivity. Comparative studies down the Fe - Ru - Os group and across the Fe - Co - Ni series will be conducted to establish periodic trends. In particular, the first transition series metal complexes are expected to react more rapidly than heavier element analogs and possess special freedom to employ 1-electron steps.The chemistry to be studied will develop a basic understanding of fundamental organometallic chemistry. The education of undergraduate, graduate, and postdoctoral students will be an important contribution of this project.

Kenneth G.博士Caulton，印第安纳州大学化学系，在化学系无机、生物无机和有机化学项目的支持下，利用[（R2 PCH 2SiMe 2）2N]-1（PNP）配体发展与金属配位的原子转移反应。提出的工作包括将原子转移到高度还原的（PNP）M或从罕见的（PNP）MG（G可以是O或N）。将研究复合物的性质，如自旋状态、键级、化学键型和空轨道和孤对电子的位置，以了解它们对化学反应性的影响。将对铁-钌-锇组和铁-钴-镍系列进行比较研究，以确定周期性趋势。特别是，第一过渡系列的金属配合物预计比重元素类似物反应更快，并拥有特殊的自由，采用1-电子steps.The化学要研究将发展基本的有机金属化学的基本理解。 本科生、研究生和博士后的教育将是本项目的重要贡献。
