Sulfur-Containing Homo- and Methanofullerenes: Synthesis and Study of Tribological Properties

Abstract

The data obtained by the authors in the field of carbon cluster chemistry, namely the catalytic cycloaddition of sulfur-containing diazo compounds to C60-fullerene under the action of complex Pd catalysts, are summarized. Cycloaddition reactions of diazoalkanes, diazoketones, and diazothioates with C60-fullerene, catalyzed by Pd(acac)2–PPh3–Et3Al, with the selective formation of new sulfur-containing methano-, homo-, and pyrazolinofullerenes, are promising as modern nanosized additives in oils for highly loaded mechanisms.
