An efficient and mild route to a series of benzo[b]thiophenes, benzo[b]furans, and dibenzofurans through gold-catalyzed benzannulation of 1-heteroarylalka-2,3-dienyl acetates was developed. Two possible pathways of this reaction involving gold carbene and aryl gold intermediates have been proposed on the basis of mechanistic studies.

Rhodium-catalyzed intramolecular C-H arylation of 2-aryloxybenzoic acids proceeded accompanied by decarbonylation to give dibenzofuran derivatives in high yields. The present reaction is widely applicable to substrates bearing various functionalities.

2-Arylphenols undergo intramolecular C-H bond activation/C-O bond formation to afford dibenzofuran derivatives under palladium catalysis in the presence of tert-butyl peroxybenzoate as an oxidant. Kinetic isotope effect experiments indicated that C-H bond cleavage is the rate-limiting step of the reaction.

supporting information; experimental part, p. 9250 - 9253 (2011/08/06)
A practical, Pd(0)/Pd(II)-catalyzed reaction was developed for phenol-directed C-H activation/C-O cyclization using air as an oxidant. The turnover-limiting step of the process was found to be C-O reductive elimination instead of C-H activation. This reaction can tolerate a variety of functional groups and is complementary to the previous methods for the synthesis of substituted dibenzofurans.
