摘要：

Sulfated anatase-titania (TiO2-SO42-) has been used as a solid acid catalyst for the synthesis of substituted pyrroles from gamma-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 TiO2-SO42- is due to its increased Bronsted acidity.
