A novel method is described for the one-pot synthesis of various ionicliquids in a competitive time. By using ultrasonicirradiation, different families of nitrogen-bearing ionicliquids can be obtained in a solvent-free or in aqueous medium, which gives a greener touch to the overall process.
used to promoteone-potsynthesis of second-generation ionic liquids (ILs), cutting down reaction times and improving yields. However, the use of chloroalkanes in the alkylation of N-heterocycles requires more drastic conditions if results are to match those obtained with more reactive alkyl halides. The present paper describes a series of MW- or MW/US-promoted IL preparations starting from chloroalkanes
