The preparation of novel fullerynes which are fullerenes (e.g. C60, C70, C80, etc.) that contain one or more alkyne functionalities and may contain additional functional groups such as hydroxyls, halogens, esters, haloesters, phenyl, oligo(ethylene glycol)s, perfluorinated alkyl chains, and the like. Two desired preparation routes are disclosed. The first one is the Fischer esterification in desired solvents using a special designed reactor in contrast to the heretofore initial Steglich reaction that results in side reactions and low yields. The second one uses acetylide Grignard reagents that have reduced nucleophilicity and higher stability in contrast to the use of heretofore initial lithium organyls or other Grignard reagents that would add to C60 with possible multi-additions in an uncontrollable manner.
制备新型
富勒烯,该
富勒烯(例如C60,C70,C80等)含有一个或多个炔基官能团,并可能含有额外的官能团,例如羟基,卤素,酯,卤代酯,苯基,寡聚(
乙二醇)和
全氟烷基等。文中介绍了两种所需的制备路线。第一种是在特定溶剂中使用特殊设计的反应器进行Fischer酯化反应,与此前的Steglich反应相比,可以避免副反应和低收率。第二种方法使用
乙炔基
格氏试剂,其亲核性降低且稳定性更高,相比于此前使用的
锂有机化合物或其他
格氏试剂,可以避免多次无法控制的加成反应。
