Abstract

Abstract : A new series of Brønsted–Lewis acidic diethyldisulfoammonium chlorometallates, [DEDSA][FeCl4 ] and [DEDSA]2 [Zn2 Cl6 ], were synthesized as solid materials from the reaction of [(Et)2 N(SO3 H)2 ][Cl] ionic liquid with transition metal chlorides (FeCl3 and ZnCl2 ) at 80 °C in neat condition for 2 h. The chlorometallates were fully characterized using various spectroscopic and analytical techniques such as Fourier transform infrared, UV–visible and Raman spectroscopies, powder X‐ray diffraction, scanning electron microscopy, energy‐dispersive X‐ray and thermogravimetric analyses, Hammett acidity and elemental analyses. Their catalytic activity was studied as reusable heterogeneous catalysts for the three‐component synthesis of novel 14‐aryl‐7‐( N ‐phenyl)‐14 H ‐dibenzo[ a, j ]acridines under solvent‐free conditions at 100 °C. Abstract : Two Brønsted‐Lewis acidic solid diethyl‐disulfoammonium chlorometallates [DEDSA][FeCl4 ] and [DEDSA]2 [Zn2 Cl6 ] were synthesized from the reaction of [(Et)2 N(SO3 H)2 ][Cl] ionic liquid with transition metal chlorides (FeCl3 and ZnCl2 ) at 80 °C and evaluated as reusable heterogeneous catalyst for preparation of novel 14‐aryl‐7‐( N ‐phenyl)‐14 H ‐dibenzo[ a, j ]acridines without solvent at 100 °C .The chlorometallates were confirmed by FT‐IR, UV/Vis, Raman, PXRD, SEM‐EDX, TGA, Hammett acidity and elemental analyses.
