Ion-paired cooperative catalysts for carbon-carbon bond formation

在这个由化学部化学催化计划资助的项目中，坦普尔大学的Graham Dobereiner教授正在开发使用一氧化碳（CO）制备重要化学品的方法。一氧化碳在化学工业中被广泛用作原料，用于形成商品化学品。因为它的使用是如此普遍，有重要的价值，在寻找新的方法来使用CO，比现在使用的更有效。在该项目中，正在开发一种新型催化剂，其中两个单独的部分在形成化学键中一起工作，以减少相对于传统方法的能源投入和资源消耗。 该研究包括与当地学校开展持续的外展计划，以及通过为对无机化学感兴趣的未来科学家组织区域会议，为学生们准备STEM劳动力。在该项目中，正在开发制备由两种带相反电荷的金属络合物组成的离子配对络合物的一般方法。目的是提供一个可调的双离子催化剂库，并建立制备稳定的双离子对催化剂所需的条件。利用这个库，催化剂被设计用于几个催化反应，包括加氢酯化和一氧化碳和烯烃的选择性共聚。除了产生有效的催化过程外，潜在的好处还包括改进对离子配对的基本理解以及无机合成的进步。

In this project funded by the Chemical Catalysis program of the Chemistry Division, Professor Graham Dobereiner of Temple University is developing methods for using carbon monoxide (CO) in the preparation of important chemicals. Carbon monoxide is widely used as a feedstock in the chemical industry for the formation of commodity chemicals. Because its use is so ubiquitous, there is significant value in finding new approaches to using CO that are more efficient than those now used. In this project a new type of catalyst, where two separate parts work together in making chemical bonds, is being developed in order to reduce energy input and decrease resource consumption relative to traditional methods. The investigation includes a sustained outreach program with local schools, as well as readying students for the STEM workforce by organizing regional meetings for future scientists with interests in inorganic chemistry.In this project, a general approach to preparing ion paired complexes composed of two oppositely charged metal complexes is being developed. The purpose is to provide a library of tunable bimetallic catalysts and to establish the conditions required for preparing stable bimetallic ion pair catalysts. Using this library, catalysts are being designed for several catalytic reactions, including hydroesterification and the selective copolymerization of carbon monoxide and alkenes. Besides yielding efficient catalytic processes, potential benefits include an improved fundamental understanding of ion pairing as well as advancements in the inorganic synthesis.
