Description:
Isolable quantities of C60, the smallest stable fullerene, have been synthesized in 12 steps from commercially available starting materials by rational chemical methods. A molecular polycyclic aromatic precursor bearing chlorine substituents at key positions forms C60 when subjected to flash vacuum pyrolysis at 1100 degrees C. No other fullerenes are formed as by-products. The methods we have developed for the target-specific synthesis of fullerenes, applied here to a synthesis of C60, should make possible the directed laboratory preparation of other fullerenes as well, including those not accessible by graphite vaporization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scott, Lawrence T -- Boorum, Margaret M -- McMahon, Brandon J -- Hagen, Stefan -- Mack, James -- Blank, Jarred -- Wegner, Hermann -- de Meijere, Armin -- New York, N.Y. -- Science. 2002 Feb 22;295(5559):1500-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Merkert Chemistry Center, Boston College, Chestnut Hill, MA 02467-3860, USA. lawrence.scott@bc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11859187" target="_blank"〉PubMed〈/a〉
