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.

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.

A simple access to metallic or onium bistrifluoromethanesulfonimide salts

Numerous salts of the (CF3SO2)2N- anion, called TFSI, were prepared according to an original one-pot procedure. First, N-benzyl trifluoromethanesulfonimide (N-benzyl triflimide) was treated with ethanol to form
