One-pot coupling facilitates biaryl synthesis using organolanthanum intermediates, highlighting the method's efficiency.
Dibenzofulvenes (DBFs) and 9,10‐phenanthrenequinones (PQs) are valuable biaryl derivatives with unique applications in many fields. The development of their synthetic methods is of great importance in organic synthesis. A one‐pot coupling reaction of 2‐bromobiaryls with ester electrophiles is reported, exploiting the exceptional reactivity of organolanthanum heterocyclic intermediates. The reaction enables precise installation of CC and CO moieties at the 2,2′‐positions of biaryl scaffolds, providing convenient access to DBFs and PQs with high efficiency and good substrate availability.
