    标题 :Synthesis of a triangulene ring system and derivatives thereof

    摘要:A three step synthesis of the 8,12-dihydro-4H-dibenzo[cd,mn]pyren-3a 2 -ylium cation (triangulenium cation) is effected by cascade cyclization of a tetra-benzyl alcohol precursor in triflic acid solution. This cation is easily observed by NMR and optical spectroscopy. Quenching of the cation into basic solutions or by hydride transfer from triethylsilane provides access to stable dihydro and tetrahydro[3]triangulenes. This route makes several [3]triangulene precursors more readily available for development of new applications in the field of molecular electronics.
