In this project in the Organic Dynamics Program of the Chemistry Division, Professor Dale F. Shellhamer in the Chemistry Department of Point Loma Nazarene College will study the reactions of xenon difluoride with unsaturated hydrocarbons in protic solvents in order to obtain a better understanding of the reaction pathway. This project will provide research training for undergraduate students. The reactions of xenon difluoride with unsaturated hydrocarbons (alkenes, unsaturated ketones, 1,3-dienes, and aromatics) in protic solvents (alcohols and water) will be investigated. A study of the kinetics and products of these reactions will allow a better understanding of the reaction mechanisms. Earlier studies on the ionic fluorination of acyclic 1,3-dienes with xenon difluoride in aprotic and protic solvents will be extended to include cyclic dienes. The stereoisomers from fluorination of cyclic dienes with xenon difluoride will be compared to previously reported data for bromination and chlorination of the same cyclic dienes.

在化学系有机动力学项目的这一项目中，罗马点拿撒勒学院化学系的Dale F.Shellhamer教授将研究二氟化氙与不饱和碳氢化合物在质子溶剂中的反应，以更好地了解反应途径。该项目将为本科生提供研究性培训。在质子性溶剂(醇和水)中，将研究二氟化氙气与不饱和碳氢化合物(烯烃、不饱和酮、1，3-二烯和芳烃)的反应。对这些反应的动力学和产物的研究将有助于更好地了解反应机理。在非质子性和质子性溶剂中，无环1，3-二烯与氙气二氟化合物的离子氟化反应的早期研究将扩展到包括环二烯。二氟化氙氟化环二烯的立体异构体将与先前报道的相同环二烯的溴化和氯化数据进行比较。
