Abstract

TiCl₂/nano-γ-Al₂O₃ as a new heterogeneous Lewis acid catalyst was synthesized and characterized by FE-SEM, XRD, FT-IR, EDS, XRF, BET and TGA. N-substituted pyrroles have been synthesized via Paal–Knorr reaction in the presence of TiCl₂/nano-γ-Al₂O₃ at room temperature under solvent-free conditions.
