Nickel-Catalyzed Direct Cross-Coupling of Aryl Sulfonium Salt with Aryl Bromide

The direct cross-couplings of aryl sulfonium salts with aryl halides could be achieved by using nickel as a reaction catalyst. The reactions proceeded efficiently via C-S bond activation in the presence of magnesium turnings and lithium chloride in THF at ambient temperature to afford the corresponding biaryls in moderate to good yields, potentially serving as an attractive alternative to conventional cross-coupling reactions employing preprepared organometallic reagents.

Pd-Catalyzed Denitrative Intramolecular C-H Arylation

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 excellent yields.

Nucleophilic substitution in O-phenyldibenzofuranium and 10-phenylxanthonium cations

Reactions of O-phenyldibenzofuranium tetrafluoroborate with nucleophiles (OH-, NO2-, AcO-) in aqueous media follow the SNAr-mechanism and involve dehydroarenes. In DMSO, this salt smoothly reacts with NO2- and I- with predominant opening of the furan ring. 10-Phenylxanthonium tetrafluoroborate readily arylates the NO2- ion in water (at the N and O atoms), mainly with predominant opening of the central ring, and is completely decomposed even with weak bases (NH2OH, 2,4-dinitrophenylhydrazine). The Baeyer -Villiger oxidation of this salt affords xanthone and 2-phenoxybenzoic acid.
