The Mechanism of Formation and the Chemical Reactivity of C60

这项来自有机动力学计划的资助支持舍夫林教授在探索性研究（SGER）计划的小额资助下的研究。本研究结果将对最近发现的具有测地线结构（Buckminster Fuller）的碳的C60同素异形体的形成机理有新的认识。此外，还将研究C60的反应。人们对这种碳的同素异形体的形成、反应和性质有着浓厚的兴趣（石墨和金刚石是碳的其他同素异形体的例子）。人们认为碳原子形成小的反应碎片，然后经过进一步的反应最终产生C60。这一假设将在旨在捕获C60的小片段前体的实验中得到验证。将可提取的氢加入到氦气中作为捕获试剂，期望捕获的碳团簇的大小与浴气压力成正比，与捕获试剂的量成反比。此外，还研究了一些活性中间体（碳烯和苯）与C60的反应。探讨了六羰基铬与C60的反应。

This grant from the Organic Dynamics Program supports the research of Professor Shevlin under the Small Grants for Exploratory Research (SGER) Program. The results of this research will give new understanding to the mechanism of formation of the recently discovered C60 allotrope of carbon, which possesses a geodesic (Buckminster Fuller) structure. In addition, reaction of C60 will be studied. There is intense interest in the formation, reactions, and properties of this allotrope of carbon (graphite and diamond are examples of other allotropes of carbon). It is thought that atomic carbon forms small reactive fragments, which then undergo further reactions to eventually produce C60. This hypothesis will be tested in experiments designed to trap the smaller fragment precursors to C60. Abstractable hydrogen will be added to the helium bath gas as the trapping reagent, with the expectation that the size of carbon clusters which are trapped will be directly proportional to bath gas pressure and inversely proportional to the amount of trapping reagent. In addition, the reactions of some reactive intermediates (carbenes and benzyne) with C60 will be studied. Reaction of chromium hexacarbonyl with C60 will also be explored.
