Surprisingly, the computational study predicted that the reaction proceeds with normal electron demand in contrast to hitherto considered inverse‐electron‐demand pathway. The benzoannulation to the pyridazine ring, i. e., phthalazine, resulted in the remarkably shortened reaction time due to the better interaction between the HOMO of phthalazine and the LUMO of C60 as well as stronger 2,3‐diaza‐1,3‐butadiene
笼式开口的双fulleroids是在富勒烯上开一个大孔的合适构件之一。这项工作的重点是迄今为止开发的合成方法中,C 60与嗪的Diels-Alder反应,以提供双富勒烯化合物。出乎意料的是,计算研究预测,与迄今考虑的反电子需求途径相反,反应以正常的电子需求进行。哒嗪环至哒嗪环,即。如酞嗪,由于酞嗪的HOMO和C 60的LUMO之间的更好的相互作用,导致反应时间显着缩短结晶学证实在酞嗪中具有更强的2,3-二氮杂-1,3-丁二烯特性。与预期相反,苯并双富勒烯通过光氧化作用比相应的哒嗪衍生的富勒烯更快地转化为相应的孔扩大衍生物。
