A new ionic liquid containing a 1H,4H-piperazine-diium ring and chlorosulfonate as a 1,4-dicationic core and counter ion, respectively, was designed and synthesised. The structure elucidation of this ionic liquid was conducted by 1D and 2D NMR, FT-IR, Raman, and mass spectrum analysis. The physical properties of this ionic liquid were determined and reported. Furthermore, the dual solvent-catalyst activity of piperazine-1,4-diium dichlorosulfonate was investigated for the synthesis of new dihydro[1,2,4]triazolo[1,5-α]pyrimidines through a one-pot three-component reaction. The ionic liquid was retrieved and reused several times without reducing its catalytic efficiency. © CSIRO 2020.
