Rhodium acetate effectively promotes the carboxylate-directed ortho-arylation of (hetero)aromatic carboxylates with aryl bromides. The main advantage of this phosphine-free, redox-neutral method arises from its efficiency in assembling biologically meaningful electron-rich arylpyridines, which are problematic substrates in known C?H arylations using Pd, Ru, and Ir catalysts.

A concise and efficient approach to a series of chromen-4-ones with fused thiophene ring has been developed using the Suzuki-Miyaura reaction of bromothiophene-2- and 3-carboxylates with 2-methoxyboronic acids and subsequent cyclization of prepared alkyl (2-methoxy)aryl thiophene-2- and 3-carboxylates under the action of BBr3/KOtBu. Starting bromothiophenes are easily obtained from corresponding commercially available aminothiophenes by diazotization/bromination reaction.

With the aim of explaining the influence of the structural changes on the biphenylic moiety on the activity, a series of N-imidazoles (I), constructed on the model of DuPont compounds by replacing either the central or terminal pheny
