Open-Cage Fullerene Derivatives Having 11-, 12-, and13-Membered-Ring Orifices: Chemical Transformations of theOrganic Addends on the Rim of the Orifice
A novel open-cage [60]fullerene derivative, having two sulfur atoms on the rim of its 13-membered-ringorifice, has been isolated and characterized. Extensive studies on the N-MEM group reactivity of this aswell as other previously reported open-cage [60]fullerene derivatives led to several new open-cage [60]fullerene adducts.
