Organoaluminum Coordination Chemistry

该奖项在无机、生物无机和有机金属化学项目中为乔治亚大学化学系的Gregory H. Robinson博士提供了持续的支持，以研究含Al-Al键的铝化合物的配位化学。目标分子的合成方法-新型有机金属alanes-将需要通过碱金属还原二芳基铝氢化物来制备含有氢化物桥和大块芳基配体的阴离子铝二聚体。二芳基铝氢化物的制备将基于类似镓化合物的合成路线。此外，将尝试使用基于二氯化铝的模板来获得所需的产品。铝的有机金属化合物直到最近才被制备出来，而且与III族的其他成员硼和镓不同，含有多个铝原子的分子很少为人所知。这类化合物的制备提出了一个合成挑战，但也可能导致具有新性质的化合物，因为该家族的其他成员在电子材料的制造中已经变得重要

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program provides continued support to Dr. Gregory H. Robinson of the Chemistry Department, University of Georgia, for investigation of the coordination chemistry of aluminum compounds containing Al-Al bonds. The synthetic approach to the target molecules--novel organometallic alanes--will require preparation of anionic aluminum dimers containing a hydride bridge and bulky aryl ligands by alkali metal reduction of diaryl aluminum hydrides. Preparation of the diaryl aluminum hydrides will be based on the synthetic route to analogous gallium compounds. In addition, attempts will be made to achieve the desired products using a template based on bis(aluminumdichloride). Organometallic compounds of aluminum have been prepared only recently, and unlike other members of the Group III family, boron and gallium, few molecules containing a multiple aluminum atoms are known. Preparation of compounds of this type presents a synthetic challenge, but also may lead to compounds with novel properties since other members of this family have become important in the manufacture of electronic materials
