项目摘要

This project, supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program, is concerned with studies of compounds that contain metal-metal multiple bonds. Objectives include 1) the synthesis of new complexes that contain M-M multiple bonds, 2) further studies of the underlying factors governing reactivity of M-M multiply bonded compounds, 3) exploration of applications of M-M multiply bonded compounds in catalytic reactions and in stoichiometric organic transformations, and 4) incorporation of M-M multiply bonded compounds in macromolecular phases such as one-dimensional polymers and liquid crystalline materials. The latter may be of interest for molecular design of materials having potentially interesting electrical, magnetic and optical properties. Whereas the existence of multiple bonds in carbon, nitrogen and oxygen compounds has been recognized for many decades, recognition of the existence of metal-metal multiple bonds is of much more recent origin. Consequently the fundamental chemistry of compounds that contain metal-metal multiple bonds is poorly developed. The primary objective of this project is to expand our knowledge of the structural and reactivity properties of compounds that contain metal-metal bonds, particularly with respect to possible applications in the catalysis of organic reactions and in the preparation of new polymers and liquid crystalline materials. The latter may prove to be useful in the development of new materials having novel electrical, magnetic or optical properties.

该项目由无机、生物无机和有机金属化学项目支持，涉及含有金属-金属多重键的化合物的研究。目标包括1）合成含有M-M多重键的新配合物，2）进一步研究控制M-M多重键化合物反应性的潜在因素，3）探索M-M多重键化合物在催化反应和化学计量有机转化中的应用， 4)将M-M多键化合物掺入大分子相，例如一维聚合物和液晶材料。后者可能对具有潜在有趣的电学、磁学和光学性质的材料的分子设计感兴趣。虽然碳、氮和氧化合物中多重键的存在已被认识了几十年，但对金属-金属多重键存在的认识却是最近才出现的。因此，含有金属-金属多重键的化合物的基础化学发展很差。该项目的主要目标是扩大我们对含有金属-金属键的化合物的结构和反应性质的了解，特别是在有机反应催化以及新型聚合物和液晶材料的制备中的可能应用。后者可能被证明可用于开发具有新颖电学、磁学或光学性质的新材料。
