高价碘介导的60富勒烯咪唑啉酮类衍生物的合成

摘要

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.%提出了一种以脲类化合物为底物,在PhI (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.
