| 摘 要： | 在Mn(OAc)3•2H2O催化下, C60分别和亚甲基二膦酸四乙酯、氰基亚甲基膦酸二乙酯或乙氧羰基亚甲基膦酸二乙酯在氯苯中回流, 生成3个单加成环丙烷富勒烯膦酸衍生物C60C(R)PO(OEt)2 [1, R＝PO(OEt)2; 2, R＝COOEt; 3, R＝CN]. 与以前报道的Bingel反应法相比, 该方法副产物少并且缩短了反应时间. 采用循环伏安法发现1, 2的还原电位相对于C60发生负移, 而3的还原电位相对于C60却正移40 mV, 表明引入象氰基一样具有很强吸电子能力的取代基团, 可以改善富勒烯球的电化学性能, 合成电子接受能力较强的富勒烯衍生物. |

| Abstract: | In the presence of manganese(III) acetate dihydrate [Mn(OAc)3•2H2O], the reaction of [60]fullerene with tetraethyl methylenediphosphonate, diethyl cyanomethylphosphonate or diethylphosphonoacetic acid ethyl ester in refluxing chlorobenzene afforded the corresponding methano[60]fullerene organophosphonates C60C(R)PO(OEt)2 [1, R＝PO(OEt)2; 2, R＝COOEt; 3, R＝CN], respectively. This reaction produced fewer by-products and needed less reaction time. Therefore it is superior to the Bingel reaction for the preparation of compounds 1, 2 and 3. In addition, compared with C60, compounds 1 and 2 had negative shifts but 3 had a posive shift of 40 mV in reduction half-wave potentials (E1/2) determined by cyclic voltammetry. These data indicate that the introduction of electro-attracting groups such as cyano-group to fullerene ball might improve the electrochemical properties and synthesize fullerene derivatives with strong electron-accepting ability. |
| Keywords: | mono-methano[60]fullerene organophosphonate synthesis electrochemical property cyclic voltammetry |
