A series of scarce fulleropyrrolines were synthesized via DMAP-mediated one-step reaction of [60]fullerene with commercially inexpensive aromatic aldehydes and arylmethanamines in the absence or presence of manganese(III) acetate. In the case of aminodiphenylmethane, novel 2,5,5-trisubstituted fulleropyrrolines could be easily obtained without the addition of manganese(III) acetate. As for arylmethanamines without α-substitutions, the addition of manganese(III) acetate was required to suppress the formation of fulleropyrrolidines, in order to generate the desired 2,5-disubstituted fulleropyrrolines. Two tautomers were produced as expected when different aryl groups (Ar ≠ Ar) from aromatic aldehydes and arylmethanamines were employed in the synthesis. A plausible reaction mechanism for the formation of fulleropyrrolines is proposed.
通过在不存在或存在醋酸锰的情况下,利用 DMAP 介导的[60]富勒烯与商业上廉价的芳香醛和芳基甲胺的一步反应,合成了一系列罕见的全吡咯啉。对于二苯甲烷胺,在不添加醋酸锰的情况下,很容易得到新型的 2,5,5-三取代全吡咯啉。对于没有α取代的芳基甲胺,需要添加醋酸锰来抑制富勒吡咯啉的形成,以便生成所需的 2,5-二取代富勒吡咯啉。当在合成中使用来自芳香醛和芳基甲胺的不同芳基(Ar ≠ Ar)时,如预期的那样产生了两种互变异构体。提出了一种形成富勒吡咯啉的合理反应机制。
