Transition-metal-free alkynylation of imidazoles with alkynyl bromides was examined in detail. With K2CO3 as base in N,N-dimethylformamide (DMF) at 80℃ for 12 h, the reaction afforded the corresponding carbon-nitrogen cross-coupling products in moderate yield. Imidazole-based aromatic ynamines were synthesized by the above method, and the structure was characterized by 1H NMR and 13C NMR spectra.

Key words: transition-metal-free, imidazoles, alkynyl bromides, C-N cross-coupling, aromatic ynamines
