  • METHOD FOR PRODUCING FULLERENE DERIVATIVE

    This method for producing a fullerene derivative is a method for producing a fullerene derivative having a partial structure shown by formula (1) by reacting a predetermined halogenated compound and two carbon atoms adjacent to each other for forming a fullerene skeleton in a mixed solvent of an aromatic solvent and an aprotic polar solvent having a C═O or S═O bond in the presence of at least one metal selected from the group comprising manganese, iron, and zinc; (in formula (1), C* are each carbon atoms adjacent to each other for forming a fullerene skeleton, A is a linking group having 1-4 carbon atoms for forming a ring structure with two C*, in which a portion thereof may be a substituted or condensed group).
    这种生产富勒烯生物的方法是通过在芳香溶剂和具有C═O或S═O键的无极性溶剂的混合溶剂中,在中选择的至少一种属存在的情况下,通过将预定卤化合物与相邻的两个碳原子反应以形成富勒烯骨架,从而产生具有由化学式(1)所示的部分结构的富勒烯生物;(在化学式(1)中,C*分别是相邻的两个碳原子,用于形成富勒烯骨架,A是具有1-4个碳原子的连接基团,用于与两个C*形成环结构,其中部分可能是取代或缩合基团)。

    DOI:10.1021/ol1029436
    日期:2011.3.18
    A facile preparation of arylmethyl and heteroarylmethyl phosphonate esters was achieved involving a Lewis acid mediated Michaelis-Arbuzov reaction at room temperature. Interaction of arylmethyl halides/alcohols with triethyl phosphite in the presence of Lewis acid at room temperature afforded phosphonate esters in good yields.
