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.

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，受无机、生物无机和有机金属化学项目的支持，研究了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官能团的反应性模式。配位环丙炔的开环和金属卟啉配合物与炔的反应是本项目的主要合成重点，炔配位对炔基连接的给受体分子和远端氧化还原位点性质的影响将在本RUI奖的支持下进行研究。炔配体具有独特的供体和受体特征，当与过渡金属结合时，提供了新的反应模式的机会。测量反应溶液中的红外吸光度和氧化还原电位的能力既提供了重要的新化学知识，也为本科研究人员提供了丰富的教育经验。
