The Chemical Structure, Dynamics and Mechanisms Program in the Chemistry Division at the National Science Foundation supports Professor Joseph Dinnocenzo of Rochester University, to provide fundamental mechanistic insight into the reactivities and reaction mechanisms of group 14 cation radical intermediates. The goal of this work is to elucidate the mechanism(s) for fragmentation reactions of aryltrialkyl-silane, -germane, -stannane, and -plumbane cation radicals. Professor Dinnocenzo will also develop methods for determining the stereochemical outcome of nucleophilic substitutions on group 14 cation radicals, and investigate the fragmentation mechanism(s) of oligosilane cation radicals.Broader impacts of the research include training opportunities for students, using orbitals and bonds to drive research in organic synthesis resulting in new chemical transformations. Potential application of this work lies in the field of polysilane photoresists. Undergraduate participation in this research will be year-round through an established REU program at the University of Rochester. Dr. Dinnocenzo is actively recruiting from underepresented groups to his laboratory.

国家科学基金会化学部的化学结构，动力学和机制计划支持罗切斯特大学的约瑟夫·迪诺科佐教授，以提供对第14组阳离子自由基中间体的反应性和反应机制的基本机械洞察力。这项工作的目的是阐明芳基三硅烷， - 甘烷， - stannane和-plumbane阳离子自由基的碎裂反应的机制。 Dinnocenzo教授还将开发用于确定14组阳离子自由基对亲核取代的立体化学结果的方法，并研究寡硅烷阳离子自由基的碎片化机制。研究的影响包括研究机会，包括使用Orbitals和Orbitals和键入有机化化学合成的新化学化学变换的培训机会。 这项工作的潜在应用在于多硅烷光孔师的领域。 本科参与这项研究的参与将通过罗切斯特大学的一项既定的REU计划全年进行。 Dinnocenzo博士正在积极招募从不遗忘的团体到他的实验室。
