- Click chemistry mediated synthesis of bio-inspired phosphonyl-functionalized ionic liquids
-
This study focuses on the synthesis of a class of novel biologically-inspired ionic liquids coupled with a phosphonate group containing short to long side chains (C3-C11) via the Pudovic reaction. The ionic liquids exhibited very low glass transition temperatures and were hydrophobic in character. This method has the attributes of click chemistry with outstanding efficiency, simplicity, yields and regioselectivity. The results of their calcium(ii) ligating capability are also presented.

- Molecular design principles of ionic liquids with a sulfonyl fluoride moiety
-
The continued success of ionic liquids in applications ranging from energy to medicine poses the challenge to rapidly find new functional ionic liquids with desirable properties while developing practical, scalable syntheses. As a SuFExable functionality, the sulfonyl fluoride has become widely adopted throughout the field of chemical biology due, in part, to its unique stability-reactivity pattern, highlighting the underappreciated potential of the SVI-F motif in materials chemistry. For the first time, we herein report the development of a set of sulfonyl fluoride-functionalized ionic liquids with considerable structural diversityviaan efficient, modular, and orthogonal fluorosulfonylethylation procedure. The resulting SO2F-functionalized ionic milieu has properties consistent with its classification as ionic liquids. We employed a combination of molecular design, synthesis, computational modeling, and X-ray crystallographic studies to gain in-depth understanding of their structure-property correlations. The diversification of the SO2F-bearing salts is extended to include active pharmaceutical precursors, allowing for access to functional materials witha priorilow toxicity.

- New process of bis-trifluoro sulfonimide salt
-
The invention provides a preparation method of a bis-trifluoro sulfonimide salt. The method comprises the following steps of S1, preparing corresponding N-alkyl-substituted bis-trifloromethane sulfonimide with primary amine and trifluoromethyl sulfonic anhydride; S2, reacting the N-alkyl-substituted bis-trifloromethane sulfonimide with a salt to obtain a crude product; S3, crystallizing the crudeproduct and then drying the crude product in vacuum to obtain the bis-trifloromethane sulfonimide salt. The method has the advantages that N-alkyl-substituted bis-trifloromethane sulfonimide is stablein property and does not generate corrosive substances in a whole reaction process, three wastes are hardly generated, the method is suitable for large-scale production, the high-purity battery-gradebis-trifloromethane sulfonimide salt can be obtained, and a high implementation value and considerable social and economic benefits are acquired.

- MOLTEN SALT COMPOSITION AND USE THEREOF
-
Molten salt compositions comprising two or more types of molten salts (MTFSI) containing imido anion (TFSI) as an anion and alkali metal (M) as a cation exhibit a lowered electrolyte melting point and an enlarged operating temperature range as compared with those of single salts. Therefore, various advantages, such as enlarging of the range of material choice in the use in battery, etc., can be brought about.
