allowing the preparation of the corresponding Grignard reagents in good yields. Furthermore, the use of a cocktail of metallic salts (Mg, ZnCl2, LiCl) in the presence of C60 fullerene (3 mol %) allows preparation of some functionalized polyaromatic zinc reagents. The resulting organomagnesium and organozinc reagents efficiently underwent reactions with electrophiles, such as an aldehyde, an acid chloride
加入催化量的C 60富勒烯(3摩尔%)可催化镁插入多环芳族卤化物中,从而可以高收率制备相应的格氏试剂。此外,在C 60富勒烯(3mol%)存在下使用金属盐(Mg,ZnCl 2,LiCl)的混合物可以制备一些官能化的多芳族锌试剂。所得的有机镁和有机锌试剂有效地与亲电子试剂如醛,酰氯,烯丙基溴或芳基碘反应。
