Chemistry of C84: Separation of Three Constitutional Isomers and Optical Resolution ofD2-C84 by Using the “Bingel-Retro-Bingel” Strategy

Abstract

The pure enantiomers of D₂ -C₈₄ as well as a third constitutional isomer of this higher fullerene were produced by a retro-Bingel reaction on the first organic derivatives of C₈₄ (see scheme). These derivatives were synthesized by Bingel cyclopropenation of C₈₄ , separated, and unambiguously structurally characterized.
