Formation of Metallacyclic C_(60) Derivatives via Gas-Phase Ion—Molecule Reactions

摘要

Since their discovery in 1985, fullerenes have drawn much attention. In 1990, Kratschmer and Huffman developed a method that made it possible to produce C_(60) and C_(70) in macroscopic quantities. Since then, the research on fullerene chemistry has boomed. In particular, a large effort has been focused on the production of fullerene derivatives through reactions involving carbon—carbon bond formation. Several routes have been taken to synthesize these derivatives including reacting C_(60) with carbon radicals, nucleophilic reagents, and electrophilic reagents. These have led to the formation of carbon bridges and cycloadditions with fullerenes. In particular, C_(60) derivatives of benzene and naphthalene have been synthesized. Organometallic complexes containing C_(60) ligands have also been prepared and characterized.
