Bis(triarylmethylium)-Mediated Diaryl Ether Synthesis: Oxidative Arylation of Phenols with N,N-Dialkyl-4-phenylthioanilines
摘要:
Various aryl 4-dialkylaminophenyl ethers were readily synthesized without heating in good yield from phenols and N,N-dialkyl-4-phenylthioanilines. This oxidative arylation of phenols was successfully promoted by a bis(diphenylmethylium)naphthalenediyl dication via ipso-substitution of the phenylthio group in the anilines through a radical process.

naphthalene-1,8-diylbis(diphenylmethylium), successfully promoted oxidative arylation of the sulfur atom in (4-N,N-dialkylaminophenyl) phenyl sulfides with (4-N,N-dialkylaminopheny)silanes, affording triarylsulfoniumsalts in good yield.
