Photochemical Reactions of Metal Carbynes

无机化学、生物无机化学和金属有机化学计划支持过渡金属配位化合物光化学领域的研究。在这个项目中，斯坦福大学的Lisa McElwee-White将研究金属碳炔的光化学反应，这将涉及到金属-碳三键的激活以及随后的反应，通过新的反应途径形成新的化合物。这项研究将对理解金属有机化合物光化学中的基本过程具有重要意义。研究的重点将是低价钼和碳化钨，例如氯代四(三甲基亚磷酸酯)-苯基碳炔，它们含有不具有光活性的辅助配体。活性金属卡宾三键的反应性研究将分为两种类型：(A)单分子反应，如配体重排或具有拴系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.
