The Mechanism of Formation and the Chemical Reactivity of C60

这笔来自有机动力学项目的资助用于支持Shevlin教授在探索性研究小额资助计划(SGER)下的研究。这一研究结果将对最近发现的具有测地线(Buckminster Fuller)结构的碳的C60同素异形体的形成机理有新的理解。此外，还将对C60的反应进行研究。人们对这种碳的同素异形体的形成、反应和性质非常感兴趣(石墨和钻石是碳的其他同素异形体的例子)。人们认为，原子碳形成小的活性碎片，然后进行进一步的反应，最终生成C60。这一假设将在旨在捕获C60的较小片段前体的实验中得到验证。可提取氢将作为捕捉剂添加到氦浴气体中，期望被捕获的碳团簇的大小将与浴气压力成正比，与捕捉剂的量成反比。此外，还将研究一些活性中间体(卡宾和苯并)与C60的反应。本课程还将探讨六羰基铬与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.
