Herein, we disclose a Cu-mediated domino di-/triarylation reaction of imidazoles to efficiently access polyaryl imidazolium salts in a single step by using two aryls as well as an anion of a diaryliodonium salt. The diarylation shows high atom economy and excellent selectivity with unsymmetrical iodonium salts.
在此，我们公开了一种 Cu 介导的咪唑的级联二芳基化/三芳基化反应，通过使用两个芳基和一个二芳基碘鎓盐的阴离子，可在一步中有效地得到多芳基咪唑鎓盐。该芳基化反应具有高原子经济性和对非对称碘鎓盐的优异选择性。
