Sulfated anatase-titania (TiO2S4 21) has been used as a solid acid catalyst for the synthesis of substituted pyrroles from diketone and aromatic/aliphatic (acyclic and cyclic) primary amines by simple physical grinding. This sulfated titania gives an excellent yield with less reaction time and is an inexpensive, easily recyclable nanocatalytic material for this reaction. Higher catalytic activity of TiO2S 4 21 is due to its increased Broonsted acidity.
