New developments in the organic chemistry of fullerenes

Journal of Physics and Chemistry of Solids, 1997

Since the discovery and isolation of macroscopic quantities of the fullerenes, the preparation of derivatives has grown rapidly over the last few years [1-3]. Functionalization of C6o in our group has been done primarily by cycloaddition reactions; particularly the 1,3-dipolar addition of diazoalkanes and alkyl azides. rt

ChemInform Abstract: Fragments of Fullerenes: Novel Syntheses and Properties

ChemInform, 1999

The utility of high-temperature gas-phase cyclization reactions for constructing bowl-shaped polycyclic aromatic hydrocarbons related to C6o was first demonstrated by our simple synthesis of corannulene, 1. This strategy has subsequently been extended to the preparation of larger fullerene fragments and promises to play a central role in future syntheses of even more spectacular molecular bowls, baskets and tubes. Isomerization reactions of benzenoid hydrocarbons at high temperatures in the gas phase have also been studied and are now known to occur by reversible benzene ring contractions to fulvene intermediates. The relationship of these small molecule rearrangements to the mechanisms of fullerene production and isomerization ("annealing") is discussed. Finally, the conversion of simple benzenoid hydrocarbons to fragments of fullerenes containing fivemembered rings with two hydrogens fewer is shown to be a common high-temperature reaction of bay region polycyclic aromatic compounds, and a preliminary mechanistic proposal is offered along with supporting experimental evidence.

Fullerenes: Synthesis and Applications

Journal of Materials Science Research, 2018

Fullerenes were initially found to be inert, but their unique cage structure and solubility in organic solvents opened up their susceptibility to functionalization via addition and redox reactions. Endohedral and exohedral derivatives of Buckminster fullerene [C60] have created a niche in the application of carbon nanomaterials in the medical, electronics, energy and water treatment/conservation sectors.
