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.

在这项由化学系化学催化计划资助的项目中，坦普尔大学的Graham Dobereiner教授正在开发在重要化学品的制备中使用一氧化碳(CO)的方法。一氧化碳在化学工业中被广泛用作形成商品化学品的原料。因为它的使用是如此无处不在，寻找比现在使用的方法更有效的使用CO的新方法具有重大价值。在该项目中，正在开发一种新型催化剂，与传统方法相比，这种催化剂可以使两个独立的部分共同作用，形成化学键，从而减少能源投入和资源消耗。调查包括与当地学校的持续外展计划，以及通过为未来对无机化学感兴趣的科学家组织地区性会议，为学生进入STEM劳动力做准备。在这个项目中，正在开发一种由两个相反电荷的金属络合物组成的离子配对络合物的一般制备方法。目的是提供一个可调双金属催化剂的文库，并建立制备稳定的双金属离子对催化剂所需的条件。利用这个文库，正在设计用于几种催化反应的催化剂，包括氢酯化反应和一氧化碳和烯烃的选择性共聚。除了产生高效的催化过程外，潜在的好处包括改善了对离子对的基本理解以及在无机合成方面的进展。
