Abstract
Regioselective ortho difunctionalization of arenes is highly desirable yet challenging in organic synthesis. Here, we briefly discuss various methods for ortho difunctionalization of arenes and highlight a novel ortho-heterobimetallic arylene complex enabled by heterobimetallic synergism, which shows great potential in regioselective ortho difunctionalizations.
