SusChEM: Polymer-Supported Frustrated Lewis Pair (FLP) Catalysis

在这个由化学系的大分子、超分子和纳米化学项目资助的项目中，位于纽瓦克的罗格斯大学的Frieder Jaekle将把通过受挫的刘易斯对（FLP）激活小分子的最新进展应用于聚合物支撑的催化。将采取多管齐下的方法：（1）将追求用强刘易斯酸（受体）和/或刘易斯碱（供体）位点（胺、膦、卡宾）官能化的可溶性聚合物，所述位点在空间上受阻以允许形成“受抑”刘易斯对。(2)还将开发含有催化活性刘易斯酸和刘易斯碱基团的多孔聚合物的创新方法。这些新材料在催化过程中的功效将被检查。除了开发可持续化学过程的社会效益外，该项目的更广泛影响包括在高度跨学科的研究环境中培训本科生和研究生，（例如ACS Project SEED高中生、少数民族本科生），并通过聚合物和材料化学外展计划建立化学可持续性意识。Jaekle教授还将于2014年在罗格斯大学纽瓦克校区组织“美洲硼”会议，拟议的工作通过开发加速化学反应的无金属催化剂来解决新的可持续化学过程的需求。所提出的催化剂的成功制备预计将在许多使用催化的领域产生影响，例如精细化学品合成，精炼和塑料制造。 此外，这项研究可能会导致新的工艺，这将减少对稀有和昂贵金属，有毒副产品以及产生的化学废物的依赖。

In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Frieder Jaekle of Rutgers University at Newark will apply recent advances in the activation of small molecules by frustrated Lewis pairs (FLPs) to polymer-supported catalysis. A multi-pronged approach will be taken: (1) soluble polymers will be pursued that are functionalized with strong Lewis acid (acceptor) and/or Lewis base (donor) sites (amines, phosphines, carbenes), which are sterically encumbered to allow for formation of "frustrated" Lewis pairs. (2) Innovative approaches to porous polymers that contain catalytically active Lewis acid and Lewis base groups will also be developed. The efficacy of these new materials in catalytic processes will be examined. In addition to the societal benefits of developing sustainable chemistry processes, the broader impacts of the project include the training of undergraduate and graduate students in a highly interdisciplinary research environment, involvement of students from groups underrepresented in chemistry (e.g. ACS Project SEED high school students, minority undergraduate students), and creating awareness of sustainability in chemistry through a Polymer and Materials Chemistry Outreach Program. The Professor Jaekle will also organize the "Boron in the Americas" meeting in 2014 at the Rutgers-Newark campus.The proposed work addresses the need for new sustainable chemistry processes by developing metal-free catalysts for accelerating chemical reactions. Successful preparation of the proposed catalysts is expected to have an impact in many areas that employ catalysis, such as fine chemical synthesis, refining, and plastics manufacturing. Additionally, this research could lead to new processes available that will reduce reliance on rare and costly metals, toxic byproducts, as well as the amounts of chemical waste generated.
