A rhodium-catalyzed decarbonylative cross-coupling reaction of benzoquinoline-10-carbaldehydes with arylboronic acids through chelation-assisted sp2 C–CHO bond activation has been developed. A variety of functional groups substituted phenylboronic acids or benzoquinoline-10-carbaldehydes are compatible with the reaction under the optimized reaction conditions, the corresponding 10-phenylbenzo[h]quinoline derivatives were obtained in moderate to good yields. The method affords a useful strategy for the synthesis of N-heterocyclic biaryl compounds via rhodium-catalyzed sp2 C–CHO bond activation.

Direct C-H arylation of nonacidic C(sp)-H bonds with primary amides as arylating reagents via highly chemoselective C-H/C-N/C-C cleavages has been accomplished for the first time. The key to the success is the cooperative combination of rhodium(I) catalys

Unsymmetrical biaryls were synthesized by oxidative coupling reactions between aromatic primary alcohols and arylboronic acids through the C-C bond cleavage of the primary alcohols chelated with a rhodium catalyst. The desired unsymmetrical biaryl products were obtained in good to excellent yields under the optimized reaction conditions. A wide variety of functionalities are compatible with the reaction under the optimized conditions. This new coupling strategy provides a favorable method to construct valuable biaryl compounds from aromatic primary alcohols which are cheap, environmentally friendly, and easily accessible substrates.

A new rhodium-catalyzed decarbonylated coupling reaction of ethyl benzo[h]quinoline-10-carboxylate and organoboron compounds that occurs through chelation-assisted sp2 C-COOEt bond activation was described. In this system CuCl played a very important role, and a five-membered rhodacycle was also involved as a key intermediate. Various functionalities were compatible in the reaction, and the desired products were obtained in good to excellent yields. DFT calculations on the mechanisms of this reaction using a Rh(I) model catalyst have also been carried out.

Go go Grignard! The first highly regioselective, cobalt-catalyzed C-H transformation of benzo[h]quinoline and phenylpyridine derivatives with Grignard reagents at room temperature has been achieved (see scheme). Both aryl and alkyl Grignard reagents showed significant reactivity.
