A Pd-catalyzed intramolecular C–H arylation of nitroarenes has been developed. Nitroarenes bearing tethered aryl groups at the ortho-position can be readily prepared in one step from 2-halonitroarenes by a nucleophilic aromatic substitution (SNAr). Under Pd/BrettPhos catalysis, activations of the C–NO2 bond as well as the C–H bond on arenes generated the corresponding biaryl linkage in moderate to
The rhodium-catalyzed intramolecular Ar–H/Ar–H coupling of 3-phenoxybenzoic acids proceeds smoothly, accompanied by double C–H bond cleavage at the 2- and 2′-positions, to produce dibenzofuran-1-carboxylic acid derivatives. Related tetra- and pentacyclic molecules can also be readily constructed by the present procedure. A reaction mechanism involving 1,4-rhodium(III) migration is proposed.
