The Synthesis, Characterization and Reactivity of Alkaline-Earth Derivatives Containing Metal-Metal Bonds

9409446 Ruhlandt-Senge锡拉丘兹大学Karin Ruhlandt-Senge博士，化学系，锡拉丘兹大学，是由化学系的无机，生物无机和有机化学计划与研究规划补助金的支持，以探索化合物的制备，其中碱土金属是键合到另一种金属。通过还原碱土金属卤化物R-M-X（R =庞大的烷基、芳基、甲硅烷基、酰氨基、硫醇基; M = Be、Mg、Ca、Sr或Ba; X = Cl、Br或I）来制备在两个第2族金属之间含有均配键的化合物。此外，含有过渡金属-碱土金属键的络合物将由金属羰基化合物或羰基化物与R-M-X或与由R-M-X还原获得的产物的反应产生。一系列的化学反应将被尝试，以探测涉及第2族原子的金属-金属键的特性。 有许多化合物含有两种或两种以上的金属键。这些物种具有多种应用，包括作为催化剂和电子材料。然而，没有很好表征的分子，其中碱土金属，即铍、镁、钙、锶或钡与另一种金属键合。在这个项目中，将设计制备这种物种的方法，并探索金属-金属键的化学性质。预计最终将用作先进材料的前体。

9409446 Ruhlandt-Senge Syracuse University Dr. Karin Ruhlandt-Senge, Chemistry Department, Syracuse University, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division with a Research Planning Grant to explore the preparation of compounds in which an alkaline earth is bonded to another metal. Compounds containing a homometallic bond between two group 2 metals will be prepared by reduction of an alkaline earth halide, R-M-X (R = bulky alkyl, aryl, sily, amido, thiolato; M = Be, Mg, Ca, Sr, or Ba; X = Cl, Br, or I). In addition, complexes containing a transition metal to alkaline earth bond will be produced from the reactions of metal carbonyls or carbonylates with R-M-X or with the products obtained from the reduction of R-M-X. A series of chemical reactions will be attempted in order to probe the characteristics of metal-metal bonds involving a group 2 atom. There are many compounds which contain two or more metals bonded to one another. These species have a variety of applications including as catalysts and electronic materials. However, there are no well characterized molecules in which an alkaline earth metal, i.e. beryllium, magnesium, calcium, strontium, or barium, is bonded to another metal. In this project methods will be devised for the preparation of such species and the chemical properties of the metal-metal bonds will be explored. Ultimate uses as precursors to advanced materials are foreseen.
