RUI: Alkane Dehydrogenation Catalyzed by CCC-Pincer Complexes of Iridium

美国国家科学基金会化学部的化学催化项目支持高露洁大学的Anthony Chianese教授开发新型的C-C-C基钳形催化剂用于烷烃脱氢反应。本工作的目标是构建各种催化剂的结构-反应性关系，这些催化剂的电子性质已经通过适当的配体取代进行了微调。烷烃功能化成α -烯烃是一个具有特殊价值的反应，对精细化工和聚合物合成领域具有重要影响。该研究的广泛影响包括开发用于新型聚合物合成的新型α -烯烃的可能性，以及新型洗涤剂和表面活性剂的潜力。例如，如果发现一种高效的催化剂，具有高选择性，可以使用丙烯作为受体并产生末端烯烃，这可能为这些重要的构建模块提供一条重要的新途径。这项研究是理想的本科院校，学生准备学习有机和有机金属合成以及一系列的光谱表征方法。中国教授积极参与高露洁夏季运动和科学营的外展活动。

The Chemical Catalysis Program in the Chemistry Division at the National Science Foundation supports Professor Anthony Chianese of Colgate University, for the development of novel C-C-C based pincer type catalysts for alkane dehydrogenation reactions. The goal of this work is to construct structure-reactivity relationships for a variety of catalysts whose electronic properties have been fine tuned with appropriate ligand substitutions. The functionalization of alkanes to alpha-olefins is a reaction of exceptional value and impacts the fine chemicals and polymer synthesis fields.Broader impacts of the research include the possibility of developing new alpha-olefins for novel polymer syntheses, and the potential for novel detergents and surfactants. For example, if an efficient catalyst is found with high selectivity that can use propylene as acceptor and yields terminal olefins, this could provide a major new route to these important building blocks. This research is ideal for an undergraduate institution, with students poised to learn organic and organometallic synthesis as well as a host of spectroscopic characterization methods. Professor Chianese is actively involved in outreach through the Colgate Summer Sport and Science Camp.
