Abstract

Abstract : Unique Lewis acid/base liquid coordination catalysts were compared to the known super acidic ionic liquid chloroaluminates and found to have higher catalytic activity in the alkylation of benzene. Abstract : Lewis acid/base catalysts of AlCl3 / N -methyl-2-pyrrolidone (O-NMP) and AlCl3 /1-methylimidazole (N-Mim) were prepared and found to have higher catalytic activity in the Friedel–Crafts alkylation of benzene than the known super acidic ionic liquid chloroaluminate [HN222 ][Al2 Cl7 ] ([HN222 ] + = triethylammonium). Crystals structures were obtained for AlCl3 (N-Mim), [AlCl2 (O-NMP)2 ][AlCl4 ], and [Al(O-NMP)6 ][AlCl4 ]3 ·(C6 H6 )3 supporting the assignments of neutral and charged catalytic species.
