an efficient synthesis of p-TolIF2 from p-TolI and Selectfluor is presented, together with a crystallographic and spectroscopic study. To mitigate safety concerns and simplify reaction execution, an HF-free protocol was devised employing CsF as a substitute fluoride source. The study provides insight into the initial I(I)→I(III) oxidation stage of the catalytic protocol using Selectfluor.

Herein we report a new general method for one-stepsynthesis of four kinds of fluoroiodane(III) reagents by treating the corresponding aryl iodides with silver difluoride (AgF2). This is the first method applicable for the synthesis of all four fluoroiodane(III) reagents including p-iodotoluene difluoride (1), fluoro-benziodoxole (2), fluoro-benziodoxolone (3), and fluoro-N-acetylbenziodazole (4).

The aryl iodides C6H5I, o-XC6H4I (X = F, I), m-FC6H4I and p-XC6H4I (X = F, Cl, Br, I, CH3, NO2) react with elemental fluorine at about −100°C in CCl3F to form the corresponding aryl iodine difluorides without attack on the aromatic ring. Preparations, 19F-nmr, 1H-nmr as well as Raman spectra are described.
芳基碘化物C 6 H 5 I,o-XC 6 H 4 I(X = F,I),m-FC 6 H 4 I和p-XC 6 H 4 I(X = F,Cl,Br,I, CH 3,NO 2)在CCl 3 F中约100°C下与元素氟反应,形成相应的芳基碘二氟化物,而不会侵蚀芳环。描述了19 F-nmr,1 H-nmr和拉曼光谱的制备方法。
