Helical Metallocene Polymers

这项授予弗吉尼亚理工学院的初学者奖金将支持保罗·A·德克教授的研究。本论文主要研究线形、均手性金属有机配位聚合物的合成与表征。各种这种聚合物材料的合成是通过合成所需的单体和链端封端络合物进行的，随后开发了在控制聚合度的情况下进行配位聚合反应的条件。然后将所得配位聚合物用作手性Lewis酸催化剂，用于有机转化，如对映体选择性的烯丙基化和缩醛反应，以及介孔环氧化物的开环反应。这一研究将促进人们对立体定向聚合物合成的基本认识。刚性、手性茂金属聚合物在不对称均相催化中得到了广泛的应用

This starter grant award to the Virginia Polytechnic Institute will support the research of Professor Paul A. Deck. The research focusses on the synthesis and characterization of linear, homochiral organometallic coordination polymers. The synthesis of a variety of such polymeric materials proceeds by synthesis of the required monomeric and chain-end-capping complexes, followed by development of conditions for carrying out the coordination polymerization reactions with control of the degree of polymerization. The resulting coordination polymers are then used as chiral Lewis-acidic catalysts for organic transformations, such as enantioselective allylation and aldolization of carbonyl compounds, as well as ring-opening of meso epoxides. The research will advance the fundamental understanding of the synthesis of stereospecific polymers. Rigid, chiral metallocene polymers have found widespread application in enantioselective homogeneous catalysis
