Helical Metallocene Polymers

这笔给弗吉尼亚理工学院的启动基金将支持Paul A. Deck教授的研究。本文主要研究线性、同手性有机金属配位聚合物的合成与表征。各种聚合材料的合成首先需要合成所需的单体和链端旋盖配合物，然后开发进行配位聚合反应的条件，控制聚合度。然后，所得到的配位聚合物被用作手性路易斯酸催化剂，用于有机转化，如羰基化合物的对映选择性烯丙基化和醛烷基化，以及介孔环氧化物的开环。该研究将促进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对映选择性均相催化中有着广泛的应用

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
