Photochemical Reactions of Metal Carbynes

无机、生物无机和有机化学 该计划支持在光化学领域的研究， 过渡金属配合物。 在这个项目中，丽莎 斯坦福大学的麦克尔维-怀特将调查 金属碳炔的光化学反应， 金属-碳三键的活化和随后的 通过新反应形成新化合物的反应 途径。 这项研究将具有重要意义 了解发生在 有机金属化合物的光化学 研究的重点将是低价钼， 钨碳炔，如氯代四（亚磷酸三甲酯）- 含有辅助配体的苯基碳炔钨， 不是光敏的。 反应性的研究 活化的金属碳炔三键将具有两种类型： (a)单分子反应如配体重排或 具有束缚官能团的分子内捕获; (b)添加试剂的双分子反应。

The Inorganic, Bioinorganic and Organometallic Chemistry Program supports research in the area of photochemistry of transition metal coordination compounds. In this project Lisa McElwee-White of Stanford University will investigate the photochemical reactions of metal carbynes which will involve activation of the metal-carbon triple bond and subsequent reaction to form new chemical compounds through novel reaction pathways. This research will be of importance in the understanding of the fundamental processes occurring in the photochemistry of organometallic compounds. The focus of the research will be low valent molybdenum and tungsten carbynes, such as chlorotetrakis(trimethylphosphite)- tungsten phenylcarbyne, which contain ancillary ligands which are not photoactive. Studies of the reactivity of the activated metal carbyne triple bond will be of two types: (a) unimolecular reactions such as ligand rearrangements or intramolecular trapping with tethered functionality; (b) bimolecular reactions with added reagents.
