Herein, we report a catalyst system for Pd-catalyzed decarbonylative Suzuki–Miyauracross-coupling of aroyl chlorides with boronic acids to furnish biaryls. This strategy is suitable for a broad range of common aroyl chlorides and boronic acids. The synthetic utility is highlighted in the direct late-stage functionalization of pharmaceuticals and natural products capitalizing on the presence of carboxylic

4,4-di-tBu-2,2-dipyridylpalladium(II) dichloride complex [(tBubpy)PdCl2] showed high efficiency for the Suzuki coupling reaction of aryl iodide and bromide with phenylboronic acid in alcohol solvent under aerobic condition. All reactions gave the isolated coupling products in moderate to excellent yields.
An environmentally benign solvent system, Solkane365/227/ethanolblend, was developed for Suzuki–Miyauracross-couplingreactions of aryl boronic acids and aryl halides. The reaction is quite general and gives excellent yields for various aryl, heteroaryl, and fluoroaryl boronic acids or halides. Interestingly, this system also allows the synthesis of polyaryls.

We report the first example of a very general Cu-catalyzed cross-coupling of organoaluminum reagents with organohalides. The reactions proceed for the couplings of alkyl-, aryl-, and alkynylaluminum reagents with aryl and heteroarylhalides and vinyl bromides, affording the cross-coupled products in good to excellent yields. Both primary and secondary alkylaluminum reagents can be utilized as organometallic

catalytic activation of arylchlorides for Suzuki–Miyaura cross‐coupling (SMC) reactions is highly challenging because of the strength of the C−Cl bond. In this work, palladium nanoparticles (Pd NPs) were grown on a conjugated nanoporous polycarbazole (CNP), named Pd/CNP. The hybrid material Pd/CNP could catalyze the SMC reactions of arylchlorides with arylboronic acids in water under blue LED irradiation
