6]fullerene-C60-Ih (1) with some anthracenes were prepared highly regioselectively by heating mixtures of the solid 1 and anthracene or of (one of) three alkyl-substituted anthracenes in the absence of solvents (Scheme 2). Other bis-cycloadducts were not detected, but lesser amounts of mono-cycloadducts 2 and 4 – 6, respectively, were also formed. Heating of solvent-free mixtures of 1 and three other alkyl-substituted
通过加热固体 1 和蒽的混合物或在没有溶剂的情况下,三个烷基取代的蒽中的一个(方案 2)。未检测到其他双环加合物,但也分别形成了较少量的单环加合物 2 和 4-6。加热 1 种和三种其他烷基取代的蒽的无溶剂混合物不会产生可检测量的(对映体)双环加合物。通过 X 射线晶体学分析了 1 和 1-甲基蒽的对映双加合物 7。加热蒽和固体 1 的制备结果与加热蒽和 1 的相应结晶单加合物的结果平行。这两种方法都揭示了反应对蒽单元上烷基取代基的存在和位置的显着一致依赖性。来自蒽和 1 的对映双加合物的区域选择性组装不能通过它们(固有的分子)稳定性来合理化,但它表明晶格的关键控制。
