Description:
In spite of their importance in fundamental and applied studies, the preparation of endohedral fullerenes has relied on difficult-to-control physical methods. We report a four-step organic reaction that completely closes a 13-membered ring orifice of an open-cage fullerene. This process can be used to synthesize a fullerene C60 encapsulating molecular hydrogen, which can be isolated as a pure product. This molecular surgical method should make possible the preparation of a series of C60 fullerenes, encapsulating either small atoms or molecules, that are not accessible by conventional physical methods.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Komatsu, Koichi -- Murata, Michihisa -- Murata, Yasujiro -- New York, N.Y. -- Science. 2005 Jan 14;307(5707):238-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Chemical Research, Kyoto University, Uji, Kyoto 611-0011, Japan. komatsu@scl.kyoto-u.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15653499" target="_blank"〉PubMed〈/a〉
