A New Method of the Preparation of Imido‐bis(sulfuric acid) Dihalogenide, (F, Cl), and the Potassium Salt of Imido‐bis(sulfuric acid) Difluoride

Abstract

The article describes a new and effective synthesis of pure imido-bis(sulfuric acid) dihalogenides (halogenide ϭ F, Cl) and the potassium salt of imido-bis(sulfuric acid) difluoride, KN(SO 2 F) 2 .

Liquid electrolyte based on lithium bis-fluorosulfonyl imide salt: Aluminum corrosion studies and lithium ion battery investigations

“…The purity of the potassium salt, characterized by its IR spectrum in Fig. 1, is a good match to the prior work of Beran and Prihoda [8]. The LiFSI was prepared by the reaction of LiBF 4 with KN(SO 2 F) 2 in acetonitrile.…”

Taming the Cationic Beast: Novel Developments in the Synthesis and Application of Weakly Coordinating Anions

“…[57] As eries of anions of generic formula [N(SO 2 R F ) 2 ] À (where R F = F, C 2 F 5 ,and C 4 F 9 ) have been prepared to modify and improve the properties of the [NTf 2 ] À anion for particular applications. [58][59][60][61] Further modification to extend the charge delocalization (and generate chirality at sulfur) has resulted in the preparation of the [F 3 CO 2 SN{(SOCF 3 N) n SO 2Àn CF 3 }] À ions,i nw hich the oxygen atoms in as ulfonyl group can be replaced by an additional NSO 2 CF 3 moiety-the so-called Yagopulskii principle. [62] The parent [NTf 2 ] À ion and its derivatives have applications in general ionic liquids, [63] electrolytes in lithium ion batteries, [50] and in metal-based Lewis acid catalysts.…”

Synthesis and Structural Characterization of a New Class of Strong Chiral Brønsted Acids: 1,1′‐Binaphthyl‐2,2′‐bis(sulfuryl)imides (JINGLEs)

“…Imidobis(sulfuryl chloride) (7) can easily be prepared according to Beran et al by heating amidosulfonic acid, thionyl chloride, and chlorosulfonic acid for 24 h under reflux. [10] www.eurjoc. For the optimization of the general method, various reaction conditions were examined.…”

“…This reagent was prepared according to Beran et al [10] Amidosulfonic acid (24.3 g, 0.25 mol), thionyl chloride (50 mL, 0.69 mol), and chlorosulfonic acid (16.5 mL, 0.25 mol) were heated under reflux for 24 h under exclusion of moisture. The product was fractionally distilled at 5.5 ϫ 10 -1 mbar.…”
