CAREER: Deciphering Reductive Transformations of Heteroallenes at Bimetallic Platforms

在这个由化学系化学催化计划资助的项目中，韦恩州立大学的斯坦尼斯拉夫·格罗伊斯曼将研究双金属平台上的合作还原转化。本项目开展的研究是出于开发新的高效二氧化碳还原催化剂的需要。二氧化碳的还原偶联为合成高链有机化学品提供了一条经济有效的途径。二氧化碳的还原裂解导致燃料、一氧化碳和甲醇的形成。本项目的目标是确定控制二氧化碳还原转化性质的因素，并为其还原开发新的催化剂。该计划的更广泛影响包括开发将二氧化碳转化为有机化学品和燃料的催化剂的潜力，以及培养受过对能源和环境领域至关重要的小分子化学教育的新一代科学家。该项目的重点是二氧化碳和相关杂烯的还原偶联和还原裂解。目标是(1)揭示二氧化碳分子化学中的关键因素，决定其还原转化的命运；(2)开发用于二氧化碳还原转化的新型分子催化剂。这些目标将通过对具有各种几何和电子参数(即金属之间的距离和辅助配体的性质)的双金属配合物的结构-反应性研究来实现。该计划的教育部分包括将小分子活化化学的短期课程纳入现有的本科生和研究生课程，与当地本科生机构开展合作研究，并培养该地区高中生对化学的兴趣。

In this project funded by the Chemical Catalysis program of the Chemistry Division, Stanislav Groysman of Wayne State University will investigate cooperative reductive transformations at bimetallic platforms. The research conducted in this project is motivated by the need to develop new efficient catalysts for carbon dioxide reduction. Reductive coupling of carbon dioxide provides a cost-efficient pathway leading to the higher-chain organic chemicals. Reductive splitting of carbon dioxide leads to the formation of fuels, carbon monoxide and methanol. The goal of the current project is to determine the factors controlling the nature of the reductive transformation of carbon dioxide, and to develop new catalysts for its reduction. The broader impacts of this program include the potential for the development of catalysts for the transformation of carbon dioxide into organic chemicals and fuels, as well as raising a new generation of scientists educated about the chemistry of small molecules crucial to the fields of energy and the environment.The focus of the project is on the reductive coupling and reductive splitting of carbon dioxide and related heteroallenes. The goals are (1) to uncover key factors in the molecular chemistry of carbon dioxide determining the fate of its reductive transformation and (2) to develop new molecular catalysts for the reductive transformations of carbon dioxide. These goals will be achieved via structure-reactivity studies on bimetallic complexes featuring various geometric and electronic parameters (i. e. the distance between the metals and the nature of the ancillary ligands). The educational components of this program encompass the incorporation of a short course on the chemistry of small molecule activation into the existing curricula of undergraduate and graduate classes, conducting collaborative research with local undergraduate institutions, and developing interest in chemistry among high-school students in the area.
