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.

Synthesis method of benzoxepine compound

The invention provides a synthesis method of a benzoxepine compound. A diarylether compound is efficiently synthesized through a reaction of a diaryl cyclic iodonium salt compound and a substrate containing a hydroxyl group, and the benzoxepine compound i
