Abstract
A versatile and modular one-pot method allows the preparation of differently substituted symmetrical and unsymmetrical imidazolium salts from readily available formamidines and α-halo ketones. For many substitution patterns of the imidazolium salt products, this efficient strategy compares favorably with well-known processes in terms of yield, ease of synthesis, and robustness.
