Perfluoroalkylation of Alkenes by Frustrated Lewis Pairs
Behrends, Ilona,B?hr, Susanne,Czekelius, Constantin
, p. 17177 - 17181 (2016)
The activation of perfluoroalkyl iodides by the frustrated Lewis pair tris(pentafluorophenyl)borane and tri-tert-butylphosphine is described. By abstraction of both a fluorine and an iodine atom, an iodophosphonium fluoroborate salt is formed. In the presence of alkenes the corresponding iodoperfluoroalkylation products are generated regioselectively. First mechanistic investigations support a radical mechanism.

The first example of visible light promoted fluoroalkylation reactions initiated via noncovalent interactions between acetone and fluoroalkyl iodides is presented. The reaction system features synthetic simplicity, mild reaction conditions without any photoredox catalyst, and high functional group tolerance. A wide range of substrate scopes such as alkenes, alkynes and (hetero)arenes were all compatible with the reaction system.

A new fluorinated anionic surfactant Cl(CF2) 6O(CF2)2SO3N(C2H 5)4 was prepared and characterized. The application of the fluorosurfactant allowed the fluoroalkylation to occur in the water without adding organic solvent. The addition of perfluoroalkyl iodides with olefins and alkynes under the initiation of Na2S2O4 in water in the presence of the fluorosurfactant gave the corresponding adducts in good to excellent yields. The fluorosurfactant was suitable for a radical addition process. A new surfactant Cl(CF2)6O(CF 2)2SO3N(C2H5) 4 was prepared and its properties were measured. The fluorinated surfactant was applied to the fluoroalkylation of perfluoroalkyl iodides with olefins and alkynes. The reactions gave the corresponding adducts in water and avoided the use of organic solvent. The aqueous solution with the surfactant proved to be an effective medium for a radical process. Copyright
