Aryl chlorides and bromides are formed from arenes in a ball mill using KHSO5 and NaX (X = Cl, Br) as oxidant and halogen source, respectively. Investigation of the reaction parameters identified operating frequency, milling time, and the number of milling balls as the main influencing variables, as these determine the amount of energy provided to the reaction system. Assessment of liquid-assisted grinding conditions revealed, that the addition of solvents has no advantageous effect in this special case. Preferably activated arenes are halogenated, whereby bromination afforded higher product yields than chlorination. Most often reactions are regio- and chemoselective, since p-substitution was preferred and concurring side-chain oxidation of alkylated arenes by KHSO5 was not observed.
A new family of phosphine ligands bearing a bulky carbazolyl scaffold is described. With the combination of ligand 2a and Pd(OAc)2, difficult tri-ortho-substituted biaryl couplings are accomplished smoothly. In particular, the catalyst loading as low as 0.02 mol% of Pd for non-activated 2,6-disubstituted aryl chloride coupling can be achieved.

A catalyst system for the preparation of biaryls containing four ortho substituents via Suzuki coupling is described. The combination of a catalytic quantity of Pd2(dba)3 with either an electron-rich biarylphosphine or DPEPhos is effective using a wide range of substrates. The X-ray crystal structure of (dba)Pd(2-(9-phenanthryl)phenyl-dicyclohexylphosphine), in which the Pd is coordinated to the 9

An efficientmethod for sterically demanding Suzuki–Miyauracoupling reactions has been developed with two catalysts, Pd/BI‐DIME (see scheme) and Pd/phenanthrene‐based ligand. The Pd/BI‐DIME catalyst facilitates the syntheses of extremely hindered biaryls bearing ortho‐isopropyl substituents. The other catalyst is efficient for the synthesis of functionalized tetra‐ortho‐substituted biaryls at low
