Copper-Catalyzed Aerobic Oxidative Reaction of C₆₀ with Aliphatic Primary Amines and CS₂

A novel type of fullerene derivatives, [60]­fullerothiazolidinethiones (<b>2</b>), were obtained from the copper-catalyzed aerobic oxidative reaction of C₆₀ with aliphatic primary amines and CS₂ in 4:1 <i>v</i>/<i>v</i> DMF and <i>o</i>-DCB. The obtained products were fully characterized with the X-ray single-crystal diffraction and spectroscopic methods. Control experiment with maleic anhydride, an analogue to C₆₀, also afforded thiazolidinethione product, but via a mechanism different from that of C₆₀ judging from the structure difference between the two types of thiazolidinethione compounds, demonstrating the unique reactivity of C₆₀

Reductive Activation of C₇₀ Equatorial Carbons and Structurally Characterized C₇₀ δ‑Adduct with Closed [5,6]-Ring Fusion

The C₇₀ δ-adducts with closed [5,6]-ring fusion are an important type of compound in classifying bond delocalization in the equatorial belt of C₇₀. However, the formation of such compounds is severely restricted due to the low reactivity of the carbon atoms in the flat equatorial region. Such a restriction is lifted when reduced anionic C₇₀ species are used, where the inert equatorial carbon atoms are activated
