Described here is the first example of solvent-promoted catalyst-free N-incorporation multicomponent domino reaction for the direct construction of novel π-extension [60]fullerene-fused dihydrocarbolines from simple hydrocarbons. This unprecedented transformation is proposed to proceed by a sequential N-incorporation/[4+2] cycloaddition/elimination process, involving multiple types of bond cleavage and formation
在此描述的是第一个通过溶剂促进的无催化剂的N结合多组分多米诺反应的例子,该反应可从简单的烃类直接构建新的π延伸[60]富勒烯稠合的二烃基。提出这种空前的转化是通过顺序的N-掺入/ [4 + 2]环加成/消除过程进行的,该过程涉及在单一化学操作中的多种类型的键裂解和形成。机理研究发现,溶剂对于成功完成转化至关重要,并且涉及多个溶剂辅助的去质子和质子转移是关键步骤。
