Abstract: A new solid catalyst was synthesized from an ionic liquid and heterogenised by changing
the anion reaction. The new heterogeneous acidic catalyst was characterized by SEM images,
EDS analysis, AFM images, Ft-IR, HNMR, 13CNMR and Mass Spectroscopy. It was applied to the
synthesis of tri-arylmethanes throughout one-pot tri-component reactions among aromatic aldehydes,
N,N-dimethylaniline and other carbonic nucleophiles such as anisole and indole. Hence, the
synthesis of convenient and inexpensive micro-heterogeneous catalyst was introduced, the efficiency
of which was confirmed. Also, various useful products were synthesized throughout this
simple and clean procedure.
