NaOH-Catalyzed Dimerization of Monofunctionalized Hydrofullerenes: Transition-Metal-Free, General, and Efficient Synthesis of Single-Bonded [60]Fullerene Dimers
NaOH-catalyzed homo- and cross-dimerizations of monofunctionalizedhydrofullerenes are reported. Various single-bondedfullerenedimers were synthesized under mild reaction conditions with remarkably high yields. The use of a NaOH catalyst combined with tetrahydrofuran as a cosolvent under an air atmosphere is critical in achieving highlyefficient catalytic dimerization.
