This research project explores the chemistry of atomic carbon with a view toward the production of a variety of novel intermediates including carbenes and strained cyclic cumulenes. Selectivity of insertion into the C-H bonds of aromatic hydrocarbons will be investigated, as will the reaction of carbon vapor with fullerenes. These latter experiments are designed to isolate and trap fullerene cages that have been modified by the addition of atomic and molecular carbon. Access to cyclic allenes is anticipated through their generation at low temperatures.With this Award, the Organic and Macromolecular Chemistry Program continues support for the research of Professor Philip B. Shevlin of Auburn University. Professor Shevlin explores the chemistry of carbon in its elemental form, unlike forms usually found in nature. Nevertheless, elemental carbon is implicated in the formation of such interesting materials as buckyballs (Buckminsterfullerenes), providing additional impetus for understanding the reactivity of atomic carbon and the reactive intermediates which can be derived from it.

本研究项目探索了原子碳的化学性质，以期生产各种新型中间体，包括碳烯和应变环积累烯。将研究碳蒸气与富勒烯的反应对芳烃C-H键插入的选择性。后一种实验旨在分离和捕获通过添加原子碳和分子碳修饰过的富勒烯笼。预期通过在低温下生成环烯可获得环烯。有了这个奖项，有机和大分子化学项目将继续支持奥本大学Philip B. Shevlin教授的研究。舍夫林教授探索了碳元素的化学性质，与自然界中常见的碳元素不同。然而，元素碳与巴克球（巴克敏斯特富勒烯）等有趣材料的形成有关，这为理解原子碳的反应性以及由此衍生的反应中间体提供了额外的动力。
