High-throughput approach for the identification of anilinium-based ionic liquids that are suitable for electropolymerisation

We report the synthesis of new protic ionic liquids (PILs) based on aniline derivatives and the use of high-throughput (HT) techniques to screen possible candidates. In this work, a simple HT method was applied to rapidly screen different aniline derivatives against different acids in order to identify possible combinations that produce PILs. This was followed by repeating the HT process with a Chemspeed robotic synthesis platform for more accurate results. One of the successful combinations were then chosen to be synthesised on a larger scale for further analysis. The new PILs are of interest to the fields of ionic liquids, energy storage and especially, conducting polymers as they serve as solvents, electrolytes and monomers at the same time for possible electropolymerisation (i.e. a self-contained polymer precursor).

Phosphoric and Phosphinic Sulfonic Anhydrides - Reinvestigation and Corrections. Novel Methods of Synthesis

Earlier works from this and other laboratories on phosphoric and phosphinic sulfonic anhydrides have been reinvestigated.It was found that no single reaction described in the past provides a general method for the production of mixed anhydrides RR'P(O)SO2R'' (3) in high yields of isolated products.The following three efficient synthetic procedures leading to pure anhydrides 3 are described: a) Trifluoromethanesulfonic acid promoted reaction of phosphinic acid 9 with sulfonic triazolides 10. b) Reaction of phosphinic and phosphoric imidazolides 13 with sulfonic acid 6. c) Reaction of 13 with sulfonic anhydride 15.All methods result in high yields.Some chemical properties of the anhydrides 3 are described.
