The reaction between trans-[AuF2(pyridine)2]+ and [PhI(pyridine)2]2+ results in the formation of PhIF2 and [Au(pyridine)4]3+. Investigation of the reaction pathway using model Pd and Pt analogues of the gold complex indicate that the most likely mechanism is attack by the Au-F onto the I(III), rather than a redox process. This demonstrates that the Au(III)-F fragment can behave in a nucleophilic manner even in a relatively electron-poor cationic complex.
Apparent electrophilic fluorination of 1,3-dicarbonyl compounds using nucleophilic fluoride mediated by PhI(OAc)2

The apparent electrophilic fluorination of 1,3-dicarbonyl compounds using Et3N·3HF as a nucleophilic fluoride source is reported. This reaction requires PhI(OAc)2 as oxidant and can be conducted safely in standard laboratory glassware. Alternative selectivity compared to Selectfluor was observed in some cases. This approach may reduce our reliance on difficult-to-handle fluorine gas and expensive electrophilic fluorinating agents derived from elemental fluorine. Mechanistic analysis related to the active fluorinating species and fluoride/acetate exchange is presented. The apparent electrophilic fluorination of 1,3-dicarbonyl compounds using Et3N·3HF mediated by the in-situ formation of PhIF2 from PhI(OAc)2 is reported. This can be performed safely in standard laboratory glassware, and this approach may reduce our reliance on difficult-to-handle fluorine gas and expensive electrophilic fluorinating agents derived from elemental fluorine.
A practical synthetic method of iodoarene difluorides without fluorine gas and mercury salts

Iodoarene difluorides were synthesized in three steps from the corresponding iodoarenes without the use of dangerous reagents such as fluorine gas of harmful mercury salts.
