โฆ Synopsis
Abstract
The synthesis of novel methanofullerene derivatives bearing a primary ammonium ion functionality is described. They are obtained by a Bingel cyclopropanation reaction on C~60~ with malonate esters, bearing both a solubilizing poly(oxyethylene) chain and an aliphatic chain ending with a BOCโprotected amine. After removal of the protecting group, a counterion exchange methodology allows for the introduction of a perfluorinated anion, bringing the overall solubility of these derivatives to 98 mg/mL in an organic CH~2~Cl~2~ solution.
