  Development of triarylamine mediator having ionic-tag and its application to electrocatalytic reaction in ionic liquid

  摘要：

  Novel triarylamine (Ar3N) mediators bearing an ionic-tag moiety were synthesized from 4,4-dibromotriphenylamine. Their electrochemical properties were investigated by cyclic voltammetry both in organic solvent and ionic liquid HF salt. The electrocatalytic reactions such as deprotection and fluorodesulfurization of dithioacetals were successfully carried out using these Ar3N mediators in an undivided cell at room temperature.

• Elemental fluorine. Part 5. Reactions of 1,3-dithiolanes and thioglycosides with fluorine–iodine mixtures

  1,3-Dithiolanes, prepared from diaryl ketones, react with elemental fluorine–iodine mixtures to give the corresponding difluoromethylene derivatives. Under the same conditions, thioglycosides give glycosyl fluorides in good yields. Reaction of 1,3-dithiolanes with fluorine in aqueous acetonitrile provides a remarkably mild method for efficient deprotection to the parent ketone.

  Nitrosonium tetrafluoroborate in conjunction with pyridinium poly(hydrogen fluoride) has been found to be excellent desulfurative fluorination reagent. In NO+BF4−/PPHF system, mono-fluorides and gem-difluordes have been obtained in high yields from the corresponding phenylsulfides and dithiolane derivatives, respectively.

  The electrochemical fluorination of organosulfur compounds in triethylamine/hydrofluoric acid (Et3N-5 HF) with polystyrene-supported iodobenzene (PSIB) and tetraethylammonium chloride (Et4NCl) was performed successfully in an undivided cell under constant current conditions to afford the corresponding fluorinated compounds in moderate to good yields. Recycle use of the PSIB could be achieved due to
