A general procedure for cobalt-catalyzed direct C–H arylation of unactivated arenes has been discovered. This method employs arylhalides as the direct coupling partners with arenes without using any Grignard-type reagents. This catalysis opens a new methodology for the preparation of symmetrical as well as unsymmetrical biaryls in a user-friendly approach.

The combination of rhodium(I) and N-hetercyclic carbenes (NHC) was found to be effective as a catalyst for cross-coupling reactions of arylarenesulfonates with arylboronicacids, which gave rise to the desired biaryl compounds in good yields.
