C_(60)负离子是合成化学中重要的前体物质.Bausch等人曾报道C_(60)Li_x与过量ICH_3反应,可生成C_(60)(CH_3)_n(n=1～24);本实验室发现,C_(60)Li_x与氯苄反应,生成C_(60)(CH_2)C_6H_5)_n(n=1～7).因此,如何提高选择性已成为至关重要的问题.最近,利用1-甲基萘作为电子转移媒介体,在THF溶液中制成一系列特定氧化态的C_(60)负离子盐.研究表明,C_(60)~(2-)离子可进行高选择性的化学修饰反应: Bausch et al. Reported that C_ (60) Li_x reacted with an excess of ICH_3 to form C_ (60) (CH_3) _n (n = 1 ~ 24). This experiment It has been found that C_ (60) Li_x reacts with benzyl chloride to form C_ (60) (CH_2) C_6H_5) _n (n = 1 ~ 7) .However, how to improve the selectivity has become a crucial issue.Recently, - methylnaphthalene as an electron transfer mediator, a series of C_ (60) anion salts with specific oxidation states were prepared in THF solution.It was found that C_ (60) ~ (2-) ions could be chemically modified with high selectivity reaction:
