Dr. Sheldon G. Shore of the Chemistry Department, Ohio State University, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program to explore avenues for the preparation and study of inorganic complexes that are composed of lanthanide metals and transition metals, either linked by an intervening group such as cyanide ion or directly coupled by lanthanide-transition metal bonds. A further aim of the proposed research is to prepare and examine transition metal and lanthanide derivatives of selected borane ligands that contain one or two boron atoms.Inorganic complexes that contain transition metals (such as nickel, palladium and platinum) display a great variety of interesting and useful properties. Many such compounds have the ability to catalyze important chemical transformations used in industrial processes and in the synthesis of new organic compounds, including pharmaceuticals. Compounds that contain both transition metal atoms and also lanthanide ("rare earth elements" such as ytterbium or gadolinium) atoms have heretofore been rare. There are good reasons to expect that such compounds, if they could be prepared, would have novel, interesting and important properties, such as the ability to catalyze chemical reactions that cannot now be catalyzed. Building on experience gained in successful research supported by NSF in the past, Shore and his colleagues will devise methods to prepare new compounds containing both lanthanide and transition-metal atoms, characterize those compounds, and explore their properties. In addition, new types of compounds containing groups of two interlinked boron atoms will also be prepared and their properties explored. Graduate students involved in this work will acquire expertise in several aspects of metal and main group chemistry, as well as in related areas of engineering and geology.

谢尔顿G博士。俄亥俄州州立大学化学系的海岸由无机，生物无机和有机物化学计划支持，以探索制备和研究由镧系金属和过渡金属组成的无机络合物的途径，这些络合物通过插入基团（如氰离子）连接或直接通过镧系元素-过渡金属键偶联。本研究的另一个目的是制备和研究含有一个或两个硼原子的硼烷配体的过渡金属和镧系元素衍生物。含有过渡金属（如镍、钯和铂）的无机配合物显示出各种有趣和有用的性质。许多这样的化合物具有催化工业过程和新有机化合物（包括药物）合成中使用的重要化学转化的能力。含有过渡金属原子和镧系元素（“稀土元素”，如镱或钆）原子的化合物迄今为止是罕见的。我们有充分的理由期待，如果能够制备这些化合物，它们将具有新颖、有趣和重要的特性，例如催化现在无法催化的化学反应的能力。 在过去NSF支持的成功研究中获得的经验的基础上，海岸和他的同事们将设计方法来制备含有镧系元素和过渡金属原子的新化合物，表征这些化合物，并探索它们的性质。此外，还将制备含有两个互连硼原子的基团的新型化合物，并探索其性质。 参与这项工作的研究生将获得金属和主族化学的几个方面的专业知识，以及工程和地质学的相关领域。
