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.

美国国家科学基金会化学部的化学催化项目支持Colgate大学的Anthony Chianese教授开发用于烷烃脱氢反应的新型C-C-C钳形催化剂。这项工作的目标是为各种催化剂构建结构-反应性关系，这些催化剂的电子性质已通过适当的配体取代进行了微调。烷烃官能化为α-烯烃是一个非常有价值的反应，它对精细化学品和高分子合成领域产生了巨大的影响，其更广泛的影响包括开发用于新型聚合物合成的新α-烯烃的可能性，以及开发新型洗涤剂和表面活性剂的潜力。例如，如果发现具有高选择性的有效催化剂，其可以使用丙烯作为受体并产生末端烯烃，则这可以为这些重要的结构单元提供主要的新路线。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光谱表征方法。Chianese教授通过高露洁夏季体育和科学营积极参与外展活动。
