Synthesis, Characterization and Application of N,N-Dimethyl-NSulfoethan Ammonium tetra-Chloro Aluminate: A Novel micro-Heterogeneous Catalyst for Synthesis of tri-Arylmethanes

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.
