Facile Bucky-Bowl Synthesis by Regiospecific Cove-Region Closure by HF Elimination

摘要

Rational synthesis of geodesic structures is of great interest, in particular as a promising method for the synthesis of individual fullerene isomers and isomerically pure single-wall carbon nanotubes. The strategy generally followed starts with the synthesis of a polycyclic aromatic hydrocarbon (PAH) containing the carbon framework required for the target molecule, which can be rolled up to the desired carbon nanostructure by aryl-aryl domino coupling. The efficiency of such a domino reaction has been demonstrated on the synthesis of I_h-C_(60) and T_d-C_(84) fullerene cages on the Pt(111) surface (Figure 1).
