将常用的有机催化剂如 N,N′-二环已基碳二亚胺、4-二甲氨基吡啶和 1-羟基苯并三唑用于亚甲基 [60 ]富勒烯羧酸的经典酯化反应 ,没有得到所期待的哑铃形偶联物 ,而得到单亚甲基富勒烯乙基酯 ,用柱色谱分离的产物经 MALPI和 FT- IR证实 ,并提出可能的反应机理。
Conventional organic catalysts such as N, N’-dicyclohexylcarbodiimide, 4-dimethylaminopyridine and 1-hydroxybenzotriazole are used for the classical esters of methylene [60] fullerene carboxylic acids The desired reaction was not obtained with the desired dumbbell-shaped conjugate to afford monomethylene fullerene ethyl ester. The product isolated by column chromatography was confirmed by MALPI and FT-IR and possible reaction mechanisms were proposed.
