A new synthetic route for the halide-free synthesis of bis(trifluoromethanesulfonyl)imide-based, hydrophobic ILs has been developed. The simple, two-step procedure could give straightforward access to a wide variety of NTf2-based ionic liquids with good yields and excellent purities. The quaternization step could be carried out under solvent-free conditions and provided high atom efficiency without additional waste formation. The reported method is intrinsically halide-free, which offers many benefits for the development of new ionic liquid-based technologies that are sensitive to halide content. The overall process is significantly less time-consuming than most reported halide-free methods and due to the reactions’ homogeneous nature, it could be successfully performed in continuous-flow operation mode. This provided an even more rapid, safe and easily scalable synthesis of the ionic liquids, allowing the to be obtained in high yields (86-99%) and productivity, with a residence time of 7.5 minutes only. The high purity renders this process not just only safe and efficient, but eventually also makes the IL products suitable for a significantly broader application range, especially for material sciences.
