Perfluoro allyl fluorosulfate (FAFS): A versatile building block for new fluoroallylic compounds
Wlassics, Ivan,Tortelli, Vito,Carella, Serena,Monzani, Cristiano,Marchionni, Giuseppe
experimental part, p. 6512 - 6540 (2011/10/13)
In this study we will present and discuss both the synthesis of CF 2=CFCF2OSO2F (perfluoroallyl fluorosulfate, FAFS), focusing in particular on the important role of C3F 6/SO3 ratio, reaction temperature and boron catalyst/SO3 ratio on FAFS' yield and selectivity, as well as a wide variety of ionic and radical reactions possible with FAFS. We focused our attention on reactions of FAFS with aliphatic and aromatic alcohols, acyl halides, halides, H2O2, ketones and radicals whose synthesis and reaction mechanisms will be presented and discussed. Particular attention will be devoted to the novel diallyl-fluoroalkyl peroxide obtained. Factors such as pKa and Lowry and Pearson's Hard/Soft Acid-Base Theory which determine the selectivity between Addition/Elimination vs. Nucleophilic Substitution reaction mechanisms on FAFS will also be presented and discussed.
The hydrofluorocarbon 1,1,1,2-tetrafluoroethane (HFC-134a) as a ready source of trifluorovinyllithium

Trifluorovinyllithium has been synthesised in high yield from 1,1,1,2-tetrafluoroethane (HFC 134a) by treatment with butyllithium at -78°C, and then treated with a variety of electrophiles in one-pot reactions.
SYNTHESIS OF PERFLUOROACRYLIC ACID FROM 3-HYDROTETRAFLUOROPROPANOL
Nguyen, T.,Wakselman, C.
, p. 97 - 99 (2007/10/02)
Perfluoroacrylic acid 1a was prepared from tetrafluoropropanol-1 2 by reaction of an alkyl lithium yielding trifluoroacrylic alcohol 3, followed by oxidation of the latter with potassium permanganate, after protection of the double bond.
