Two new methanofullerenes, C60(CHCN) and C60(CBr2), have been prepared by treating a mixture of [60]fullerene and either CH2BrCN or CHBr3 respectively with LDA. The products were purified by silica gel column chromatography, characterised by EI-MS and IR, and shown by 13C NMR to consist solely of 6-6 ring junction adducts.
通过分别用LDA处理[60]富勒烯与CH 2 BrCN或CHBr 3的混合物,制备了两种新的亚甲基富勒烯C 60(CHCN)和C 60(CBr 2)。产物通过硅胶柱色谱法纯化,通过EI-MS和IR表征,并通过13 C NMR显示仅由6-6个环结加合物组成。

powerful methods for the functionalization of these macromolecular forms of syntheticcarbonallotropes (SCAs). Activation of C60 by negative charging represents a little explored concept of fullerene chemistry, providing both new insights of fullerene reactivity itself and new types of exohedral derivatives.
