RUI: The metal-alkyne interaction: Influence on reactivity and physical properties.

Michael Shaw是南伊利诺伊大学爱德华兹维尔分校化学系的一名教员，他得到了无机，生物无机和有机化学计划的支持，以研究配位炔中电子密度的重新分布如何改变炔配体的有用物理性质以及炔三键和直接连接的官能团的反应模式。本项目的主要合成方向是环丙基炔配位化合物的开环反应和金属卟啉与炔的反应，并将在RUI奖的支持下探索炔配位对炔基连接的给体-受体分子和远程氧化还原位点性质的影响。炔配体具有独特的给体和受体特性，当与过渡金属结合时，提供了新的反应模式的机会。 测量反应溶液中红外吸收和氧化还原电位的能力为本科研究人员提供了重要的新化学知识和丰富的教育经验。

Michael Shaw, a faculty member in the Department of Chemistry at Southern Illinois University at Edwardsville, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program to investigate how the redistribution of electron density in coordinated alkynes alters useful physical properties of the alkyne ligand and reactivity patterns of both the alkyne triple bond and directly attached functional groups. Ring opening of coordinated cyclopropylalkynes and reactions of metal porphyrin complexes with alkynes are the major synthetic thrusts of this project, and the effect of alkyne coordination on properities of alkynyl linked donor-acceptor molecules and remote redox sites will be probed with support from this RUI award.Alkyne ligands have unique donor and acceptor characteristics that offer opportunities for new reactivity patterns when bound to transition metals. The ability to measure infrared absorbances and redox potentials in reaction solutions provides both important new chemical knowledge and also a rich educational experience for undergraduate researchers.
