前所未有的，无过渡金属naoh催化的单官能化氢富勒烯的同源和交叉二聚化被报道。在温和的反应条件下合成了多种单键富勒烯二聚体，收率很高。在空气气氛下使用氢氧化钠催化剂与四氢呋喃作为共溶剂是实现高效催化二聚化的关键。
Unprecedented, transition-metal-free NaOH-catalyzed homo- and cross-dimerizations of monofunctionalized hydrofullerenes are reported. Various single-bonded fullerene dimers 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 highly efficient catalytic dimerization.
