• address such questions, we report here on the synthesis and physical characterization of some phosphonium analogues to pyrrolidinium and piperidinium ILs, i.e. phospholanium and phosphinanium ILs respectively. The favorable stability of phosphonium ILs makes them good choices for applications where the IL
