Gold Catalyzed Polymerizations

国家科学基金会化学部的化学催化计划支持康涅狄格大学的Alexandru Asandei教授开发新型金基有机金属聚合催化剂。这项工作的目的是了解金周围各种氧化态的配位体性质的平衡，这是实现加成、缩合、配位和自由基聚合所必需的。可能的底物包括二炔、二烯和二羰基。这项研究的性质是一项调查，对配体设计、催化剂性质和所需的聚合反应采取了“大致”的方法。就更广泛的影响而言，这项研究的大部分在化学反应方面是未知的领域，并有可能导致许多新的和有趣的材料。拟议的调查涉及一种全面而合理的方法，以寻找金催化在聚合物化学中的机会和应用，基于当前有机/有机金属金化学发展的知识，并根据既定的聚合原理。Asandei教授的总体目标是能够通过适当的催化剂设计来“调整”材料的性质。这项工作适合本科生的研究，并将通过在当地高中的研讨会向社区进行重大推广。

The Chemical Catalysis Program in the Chemistry Division at the National Science Foundation supports Professor Alexandru Asandei of the University of Connecticut, for the development of novel gold-based organometallic polymerization catalysts. The goal of this work is to understand the balance of ligand properties surrounding gold in various oxidation states needed to effect addition, condensation, coordination and free radical polymerizations. Possible substrates include diynes, dienes, and dicarbonyls. The nature of this research is that of a survey, taking a "broad strokes" approach to ligand design, catalyst properties, and the desired polymerization reactions.In terms of broader impacts, much of this research is uncharted territory in terms of chemical reactivity and has the potential to lead to many new and interesting materials. The proposed investigations concern a comprehensive but rational approach to finding opportunities and applications of gold catalysis in polymer chemistry, based on knowledge emerging from current organic/organometallic Au chemistry developments, and from established polymerization principles. Professor Asandei has the general goal of being able to "tune" material properties with appropriate catalyst design. The work is amenable to undergraduate research, and there will be significant outreach to the community through workshops in local high schools.
