Reported herein, for the first time, is a copper-promoted intramolecular [4+2]-cycloaddition cascade to access ionic N-doped polycyclic aromatic hydrocarbons (PAHs) with tunable emission wavelengths. It is shown that the reaction can be made catalytic with respect to Cu(OTf)2 when an external oxidant, Selectfluor, was used.
本文首次报道了铜促进的分子内[4 + 2]-环加成级联反应,以访问具有可调发射波长的离子N掺杂多环芳烃(PAH)。结果表明,当使用外部氧化剂Selectfluor时,对于Cu(OTf)2可以使反应催化。
