Abstract 2-[(1 H -imidazol-3-ium-3-yl)methyl]-4-bis[3-((1 H -imidazol-3-ium-3-yl) methyl-(4-hydroxyphenyl]methylene}cyclohexa-2,5-dienone trihydrogen sulfate ([2-(imm)-4-b(immh)m}c][HSO4]3), as the new Bronsted acidic ionic liquid, is effectively prepared and revealed by using FTIR, 1H NMR, SEM, EDS, XRD and mass data. Afterward, its catalytic activity was investigated for the synthesis of 2,4,5-trisubstituted
