Enamines with in situ formed hydrogen fluoride underwent efficient reaction with trimethyl(1,1,2,2-tetrafluoro-2-(phenylthio)ethyl)silane and trimethyl(1,1,2,2-tetrafluoro-2-(phenylsulfonyl)ethyl)silane. Radical or reductive desulfurization of the additio

A modular synthetic method, involving a hydrothiolation, silylation, and fluoroalkylation, for the construction of highly functionalized fluoroalkyl sulfides has been developed. The use of aprotic polar solvents enables the additive-free chemoselective hydrothiolation of tetrafluoroethylene, trifluorochloroethylene, and hexafluoropropene with various thiols. The stepwise functionalization reactions convert the hydrothiolated intermediates into the tetrafluoroethyl sulfides in high efficiency. The method avoids the use of the environmental pollutant Halon-2402, which was employed as a building block in a reported synthetic route.

Global interest in the "CF2CF2" building blocks (tetrafluoroethylene, tetrafluoroethyl) is still rather marginal. One of the main reasons is the lack of efficient and selective tetrafluoroethylation reagents. In this context, we pres

This paper reports both on a general multistep synthesis of a wide family of aryl substituted perfluorosulfonimides and on a preliminary electrochemical investigation of two lithium salts hosted by a poly(oxyethylene) homopolymer. Both salts have a cationic transference number more than twice that of LiTFSI. Additionally, one of these salts exhibits markedly higher cationic conductivities than POE/LiTFSI electrolytes. These preliminary data are very encouraging as, thanks to the aryl moiety, a wide variety of salts can be considered in order to still improve the performances of polymer electrolytes.
AROMATIC SULPHONYLIMIDES, PREPARATION THEREOF AND USE THEREOF AS ELECTROLYTE

Page/Page column 6, (2010/07/10)
The invention relates to a process for preparing aromatic sulphonylimides, to the sulphonylimides obtained, and to the use thereof as salt of an electrolyte. The sulphonylimides correspond to the formula [R—SO2—N—SO2R′]rM (I). R′ is an ArZL- group. R′ is a perfluoroalkyl group or an ArZL- group. Z is an S, SO or SO2 group. L is a —(CF2)n—CFRf— group. n is 0 or 1; Rf represents F or a C1 to C8 perfluoroalkyl group; Ar is an aromatic group. M represents H, an alkali metal cation, an alkaline earth metal cation, a trivalent or tetravalent metal cation, or an organic cation. The process consists in preparing a compound RSO2N(R′)SO2R′ from RSO2F, and in replacing the group R′ by nucleophilic substitution reaction so as to obtain the compound (I), R′ being a benzyl or trimethylsilyl group.

Several aryl-containing ammonium sulfonates have been prepared either by cationic metathesis from the corresponding lithium sulfonates or from the corresponding sulfonic acids. The latter have been obtained by elution of an Amberlite resin with alcoholic
An efficient preparation of new sulfonyl fluorides and lithium sulfonates

(Formula Presented) An efficient preparation of several polyfluoroalkanesulfonyl fluorides is reported. This method, based on the synthesis of polyfluoroalkyl trimethyl silanes (precursors of polyfluoroalkylsulfinates) as intermediates, allows the successive transformations to be carried out in one pot. Moreover, these sulfonyl fluorides can be obtained from the corresponding sulfinates by electrophilic fluorination. This original approach avoids isolation and purification of some thermally or hydrolytically unstable intermediates. A series of new sulfonyl fluorides have been thus prepared from halogenodifluoromethylated precursors RCF2X (X = F, Br; R = ArC(O), ArS(O)n(CF2) m; n = 0, 1, 2; m = 1, 2) and have been transformed into the corresponding lithium sulfonates, which have potential applications as electrolytes for lithium batteries.
