亲核加成是Fullerene[60]典型、特征的反应,由于富勒烯分子有很多反应活性点,大多数亲核取代发生多元加成,生成难分离的混合物。Fullerene[60]和氰化钠的加成反应证明:以N,N-二甲基甲酰胺和邻二氯苯为混合溶剂,氰基负离子(CN-)与C60能发生可控的一元亲核加成反应,生成[C60(CN)]-,不分离此中间体,直接加入三氟乙酸得到产物C60(CN)H;如果在C60(CN)-的溶液中加入对甲苯磺酰氰,可高收率地得到C60(CN)2。利用1H NMR、质谱、元素分析对产物的组成和结构进行了确认和鉴定。
Nucleophilic addition is a typical and characteristic reaction of Fullerene [60]. Because fullerene molecules have many reactive sites, most nucleophilic substitutions undergo multiple additions to form an intractable mixture. The addition reaction of Fullerene [60] and sodium cyanide proved that the mononuclear nucleophile can be controlled by the cyano anion (CN-) and C60 with N, N-dimethylformamide and o-dichlorobenzene as the mixed solvent Addition reaction to produce [C60 (CN)] -, without isolating this intermediate, adding trifluoroacetic acid directly to give the product C60 (CN) H; if p-toluene sulfonyl cyanide is added to a solution of C60 C60 (CN) 2 was obtained in high yield. The composition and structure of the product were confirmed and identified by 1H NMR, MS and elemental analysis.
