摘　　要：提出了一种以脲类化合物为底物,在Ph I(OAc)2/I2催化体系下与富勒烯[60]反应制备出富勒烯咪唑啉酮类衍生物的方法。考察了反应时间、反应温度、催化剂种类以及反应物计量比等因素对反应的影响,确定了适宜的反应条件,并提出了催化反应的机理,同时研究了所合成富勒烯咪唑啉酮衍生物的电化学性质。该方法具有操作简单、原料易得、条件温和、非过渡金属催化等特点。This paper reports a simple method for the synthesis of the fulleroimidazolidinones derivatives from ureas using the PhI（OAc）2/I2 as the catalytic system. The effects of the reaction time,reaction temperature,types of catalysts and the material ratio of reactants on the reaction were investigated,with the optimum reaction conditions been confirmed. Moreover a possible reaction mechanism was proposed as well as the electrochemical properties of obtained fulleroimidazolidinone derivatives were studied. The advantages of this strategy include simple operation,readily available raw materials,mild reaction conditions,non- transition metal catalysis,etc.
