The reaction of XeF2 with some organo-phosphorus, -arsenic and-iodine compounds is described. The products were identified by fluorine nmr spectroscopy and the conditions under which fluorine exchange occurs were briefly investigated. Organoiodine (III) difluorides are suitable for the conversion of Ph2Te to Ph2TeF2; the decomposition of RIF2liberates IF and fluoroalkane.

CsSO4F reacted at room temperature, or at 35°C in acetonitrile with various heteroatom-containing organicmolecules, and three types of transformations have been observed. Fluoro substitution process took place with triphenylmethane, triphenylsilane, triphenylchlorosilane, 4-tert-butylphenol, benzaldehyde, and octanal, thus forming fluorotriphenylmethane, fluorotriphenylsilane, 2-fluoro-4-tert-butylphenol

N-Iodosuccinimide reacted with phenyl substituted alkenes in the presence of insoluble polymer supported hydrogenfluoride, which was prepared by reaction of hydrogenfluoride with crosslinked poly(styrene-co-4-vinylpyridine) containing 40–45 mol% of 4-vinylpyridine, thus forming vicinal iodofluorides in high yields. Reactions proceeded with Markovnikov type regioselectivity, and in the case of (Z)-

Room-temperature fluorination of pentane-2,4-dione with CsSO4F gave 3-fluoro and 1,3-difluoro derivatives, while 5,5-difluorobarbituric acid was formed in high yield in a 2 h reaction at 100 °C; 1,3-dimethyluracil was converted in methanol via cis- and trans-5-fluoro-6-methoxy derivatives into 5-fluoro-1,3-dimethyluracil in high yield and uridine into 5-fluorouridine.

Regio-, stereo-, and chemoselective halofluorination of alkenes is achieved using N-haloamides and tetrabutylammonium dihydrogentrifluoride, and the resulting F-I adducts were successfully converted into fluoroalkenes under dehydroiodination with 1,8-diazabicyclo[5.4.0]undec-7-ene.
