Free Radical and Photochemical Reactions of Organophosphorus Systems

有机动力学计划支持犹他大学化学系的韦斯利·G·本特鲁德教授对有机磷体系的自由基和光化学反应的研究。本特鲁德教授正在探索使用三配位磷分子作为双自由基中间体的陷阱，并通过磷酰基自由基化学的新用途来选择性地转移和功能化自由基中间体。电子结构对烯丙基亚磷酸三酯三重态敏化分子内光重排效率的影响，三配位磷分子自由基阳离子的环化和裂解反应，以及光-Arbuzov重排的自由基对和协同性质的基本方面也在研究中。在有机动力学项目的支持下，犹他大学化学系的韦斯利·G·本特鲁德教授研究含磷分子的化学。这些化合物存在于许多重要的环境中，实际应用于抗氧化剂、燃料添加剂、抗肿瘤和抗病毒药物，也是许多生化转化的关键中间体。通过发现含磷分子的新反应并阐明这些反应发生的途径，本特鲁德教授对我们对这些重要化合物的化学有了基本的了解。

The Organic Dynamics Program supports Professor Wesley G. Bentrude, of the Department of Chemistry at the University of Utah, for his studies of free radical and photochemical reactions of organophosphorus systems. Professor Bentrude is exploring the use of three-coordinate phosphorus molecules as traps for biradical intermediates and the selective diversion and functionalization of free radical intermediates through new uses of phosphoranyl radical chemistry. Fundamental aspects of the influence of electronic structure on the efficiencies of triplet-sensitized intramolecular photorearrangements of allyl phosphite triesters, cyclization and fragmentation reactions of radical cations of three-coordinate phosphorus molecules, and the radical pair vs. concerted nature of the photo-Arbuzov rearrangement are also under investigation. With the support of the Organic Dynamics Program, Professor Wesley G. Bentrude, of the Department of Chemistry at the University of Utah, studies the chemistry of phosphorus-containing molecules. Such compounds are found in a number of important settings, with practical applications as antioxidants, fuel additives, and antitumor and antiviral agents, and are also key intermediates in a number of biochemical transformations. Through the discovery of new reactions of phosphorus-containing molecules and elucidation of the pathways by which these reactions occur, Professor Bentrude contributes to our fundamental understanding of the chemistry of these important compounds.
