Chemical equations presented. The first example of the rhodium-catalyzed O-arylation of aryl bromides is reported. While the right combination of rhodium species and N-heterocyclic carbene (NHC) offered an effective catalytic system enabling the arylation to proceed, the choice of NHC was determined to be most important. The developed O-arylation protocol has a wide range of substrate scope, high functional group tolerance, and flexibility allowing a complementary route to either N- or O-arylation depending on the choice of NHC.

Highly selective coupling of diiodoarenes with phenols or phenthiols can be performed by using a low-cost, benign character and readily available Fe/Cu catalytic system in the absence of ligands. It is noteworthy that the desired dimeric aryl ethers or sulfides could be obtained in high yields by coupling between diiodoarenes and phenols, or diphenols with aryl iodides.

A highly efficient and readily available catalyst system for O-arylation of various phenols using CuI and (S)-N-methylpyrrolidine-2-carboxamide (Pro-NHMe) was developed. The reaction is widely applicable to the synthesis of diaryl ethers. Georg Thieme Verlag Stuttgart.

Oligomers of p-phenylene oxides have been synthesized by coupling of substituted phenols and aryl bromides in the presence of cuprous chloride. The chain length varies from 2 to 5 phenyl rings functionalized at one end by an OH and OMe group and at the other end by an OH, OMe or NO2 functions. The oligomers could be used in material science and as building blocks in supramolecular chemistry. Methods for chemoselective demethylation of methoxy groups were developed.
