intramolecular condensation of benzo[c]phenanthrene under flash vacuum pyrolysis conditions. Methyl and fluorine functionalization were found to be promising approaches. Unexpectedly high selectivity was observed in the cyclization of fluorinated benzo[c]phenanthrenes. The mechanism for the condensation reaction and the advantages of fluorine as a promoter for the rational synthesis of fullerenes are discussed
已经测试了各种官能团作为苯并 [c] 菲在快速真空热解条件下分子内缩合的替代促进剂。发现甲基和氟官能化是有前途的方法。在氟化苯并[c]菲的环化中观察到了出乎意料的高选择性。讨论了缩合反应的机理和氟作为促进富勒烯合理合成的促进剂的优势。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
