Isolation of Fullerene Products from Flames: Structure and Synthesis of the C60‐Cyclopentadiene Adduct.

Abstract A C 60 -C 5 H 6 adduct was isolated from a low pressure benzene flame. The structure of this product is identical to the Diels-Alder adduct of C 60 and cyclopentadiene as established through independent synthesis. This product was determined to be adduct 1 through 13 C and proton NMR, as well as infrared and mass spectrometry.
